When git is compiled with the MIPSpro 7.4.4m compiler, and NO_PTHREADS is
set, and NO_MMAP is _not_ set, then git segfaults when trying to access the
first entry in a reflog. If NO_PTHREADS is not set (which implies that the
pthread library is linked in), or NO_MMAP _is_ set, then the segfault is
not encountered. The conservative choice has been made to set NO_MMAP in
the Makefile to avoid this flaw. The GNU C compiler does not produce this
behavior.
The segfault happens in refs.c:read_ref_at(). The mmap succeeds, and the
loop is executed properly until rec is rewound into the first line (reflog
entry) of the file. The segfault is caught by test 28 of
t1400-update-ref.sh which fails when 'git rev-parse --verify "master@{May 25
2005}"' is called.
So, add a comment in the Makefile to describe why NO_MMAP is set and as a
hint to those who may be interested in unsetting it.

Since commit dcda3614 removed the use of a variable length array from
builtin-pack-objects.c, it is now safe to compile with the threaded delta
search feature enabled. Formerly, the MIPSpro 7.4.4m compiler warned that
variable length arrays should not be used with pthreads.

In the MSVC section of the Makefile, BASIC_CFLAGS is set to a
value which contains the string "-DWIN32-D_CONSOLE". This results
in a (single) malformed -Define being passed to the compiler.
At least on my cygwin installation, the msvc compiler seems to
ignore this parameter, without issuing an error or warning, and
results in the WIN32 and _CONSOLE macros being undefined. This
breaks the build.
In order to fix the build, we simply insert a space between the
two -Define parameters, "-DWIN32" and "-D_CONSOLE", as originally
intended.

The Makefile comment for NEEDS_SSL_WITH_CRYPTO says to define it "if
you need -lcrypto with -lssl (Darwin)." However, what it actually
does is add -lssl when you use -lcrypto and not the other way around.
However, libcrypto contains a majority of the ERR_* functions from
OpenSSL (at least on OS X) so we need it both ways.
So, add NEEDS_CRYPTO_WITH_SSL which adds -lcrypto to the OpenSSL link
flags and clarify the difference between it and NEEDS_SSL_WITH_CRYPTO.

It is true that NEEDS_RESOLV is needed on SunOS if NO_IPV6 is set since
hstrerror() resides in libresolv, but performing this test at its current
location is not very useful. It will only have any effect if the user
modifies the make variables from the make command line, and will have no
effect if a config.mak file is used. A better location for this
conditional would have been further down in the Makefile after the
config.mak and config.mak.autogen had been parsed. Rather than adding
clutter to the Makefile for a conditional that will likely never be
triggered, just remove it, and any user on SunOS that manually sets NO_IPV6
can also set NEEDS_RESOLV.

transport_get() can call transport_native_helper_init() to have list and

either their hashes or what they are symrefs to, while the latter
fetches them into the local object database and prints a newline when done.

The first "grep -C1" test in t7002 does not pass on my SunOS-5.11-i86pc,
and that is not because our way to spawn external grep is broken, but
because the native grep does not understand -C<n>.
It turns out that Peff was also using this option himself because our
Makefile doesn't do that automatically. Brandon Casey uses SUNWspro
compiler without having to set this, and it turns out that the compiler
does not define preprocessor macro __unix__ which made him always use the
built-in grep, never an external one.
Let's be more explicit and say that we do not use external grep on Suns.

When a git command executes a subcommand, it uses the "git
foo" form, which relies on finding "git" in the PATH.
Normally this should not be a problem, since the same "git"
that was used to invoke git in the first place will be
found. And if somebody invokes a "git" outside of the PATH
(e.g., by giving its absolute path), this case is already
covered: we put that absolute path onto the front of PATH.
However, if one is using "sudo", then sudo will execute the
"git" from the PATH, but pass along a restricted PATH that
may not contain the original "git" directory. In this case,
executing a subcommand will fail.
To solve this, we put the "git" wrapper itself into the
execdir; this directory is prepended to the PATH when git
starts, so the wrapper will always be found.

In an earlier patch, we introduced SANE_TOOL_PATH that is prepended to
user's PATH. This had an unintended consequence of overriding user's
private binary directory that typically comes earlier in the PATH to holds
even saner commands than whatever comes with the system.
For example, a user may have ~/bin that is early in the path and contains
a shell script "vi" that launches system's /bin/vi with specific options.
Prepending SANE_TOOL_PATH to the PATH that happens to have "vi" in it
defeats such customization.
This fixes the issue by inserting SANE_TOOL_PATH just before /bin or
/usr/bin appears on the PATH.

Some platforms (like SunOS and family) have kept their common binaries at
some historical moment in time, and introduced new binaries with modern
features in a special location like /usr/xpg4/bin or /usr/ucb. Some of the
features provided by these modern binaries are expected and required by git.
If the featureful binaries are not in the users path, then git could end up
using the less featureful binary and fail.
