Throughout git, it is assumed that the WIN32 preprocessor symbol is defined on native Windows setups (mingw and msvc) and not on Cygwin. On Cygwin, most of the time git can pretend this is just another Unix machine, and Windows-specific magic is generally counterproductive. Unfortunately Cygwin *does* define the WIN32 symbol in some headers. Best to rely on a new git-specific symbol GIT_WINDOWS_NATIVE instead, defined as follows: #if defined(WIN32) && !defined(__CYGWIN__) # define GIT_WINDOWS_NATIVE #endif After this change, it should be possible to drop the CYGWIN_V15_WIN32API setting without any negative effect.

/*

|
* This program can either change modification time of the given
|
|
* file(s) or just print it. The program does not change atime nor
|
|
* ctime (their values are explicitly preserved).
|
|
*
|
|
* The mtime can be changed to an absolute value:
|
|
*
|
|
* test-chmtime =<seconds> file...
|
|
*
|
|
* Relative to the current time as returned by time(3):
|
|
*
|
|
* test-chmtime =+<seconds> (or =-<seconds>) file...
|
|
*
|
|
* Or relative to the current mtime of the file:
|
|
*
|
|
* test-chmtime <seconds> file...
|
|
* test-chmtime +<seconds> (or -<seconds>) file...
|
|
*
|
|
* Examples:
|
|
*
|
|
* To just print the mtime use --verbose and set the file mtime offset to 0:
|
|
*
|
|
* test-chmtime -v +0 file
|
|
*
|
|
* To set the mtime to current time:
|
|
*
|
|
* test-chmtime =+0 file
