Enhance code to pass compiler warning. Prior to this change the
compiler would complain with the following message:
error: ISO C++ says that these are ambiguous, even though the worst
conversion for the first is better than the worst conversion for the
second: /usr/include/c++/4.5/bits/postypes.h:192:7: note: candidate 1:
std::fpos<_StateT> std::fpos<_StateT>::operator-(std::streamoff) const
[with _StateT = __mbstate_t, std::fpos<_StateT> =
std::fpos<__mbstate_t>, std::streamoff = long int] Utils.cc:443:27:
note: candidate 2: operator-(std::streamoff, long long int) <built-in>
Add code to handle situation where realpath might return a NULL value.
Prior to this change the compiler would complain with the following
message:
error: ignoring return value of ‘char* realpath(const char*, char*)’,
declared with attribute warn_unused_result
Removed expression that is always true. Prior to this change the
compiler would complain with the following message:
error: comparison of unsigned expression >= 0 is always true
Add code to handle situation where mkdtemp(char*) function returns
with a NULL value. Prior to this code the compiler would complain
with the following message:
error: ignoring return value of ‘char* mkdtemp(char*)’, declared with
attribute warn_unused_result
Some classes contained private attributes which were used only by a single
member function. Such items were moved to the corresponding function implementations
to stress their limited usage scope.
A few unused variables were also deleted.

The release of (lib)parted 3.0 includes a change to the Application
Programing Interface - API. Most importantly, libparted 3.0 removes
many file system specific function calls, and hence the capabilities
provided by these functions. In order for GParted to compile and link
with libparted 3.0, this libparted functionality is lost.
Specifically, the functionality that is lost when GParted is compiled
and linked with libparted 3.0 is as follows:
- Loss of ability to grow and shrink FAT16 and FAT32 file systems
- Loss of ability to shrink HFS and HFS+ file systems
- Loss of ability to determine used and unused sectors in HFS and
HFS+ file systems
- Loss of ability to erase file system signatures on partition
create and format
It is hoped that other free software projects will include some or all
of the above lost functionality, which can then be added back to
GParted.
This commit includes a change in how FAT16 and FAT32 file systems are
moved. Specifically the move is now performed internally by GParted
when linked with libparted 3.0. The move functionality is provided by
libparted for prior libparted versions (e.g. less than 3.0).
This is the final enhancement in a series of commits that enable
GParted to compile with libparted version 3.0.
Closes Bug #651559 - Doesn't compile against parted 3.0
On disks with an unrecognized disk label, the end sector value
was saved as one sector larger than actual. This caused the
Partition Information dialog to report the end sector value and
the total number of sectors on the disk as one larger than the
actual value.
Closes Bug #649444 - Partition information reports wrong sector
count
