AFAICT this was added for MinGW at the beginning of the century.
MSVC does not need it, mingw-w64 does not need it. Some old Cygwin
1.7.x I had lying around did need it, however, a freshly installed
Cygwin 2.5.x does not need it. MinGW 3.22.1 needs it, which probably
only shows how obsolete MinGW really is. MinGW 3.22.1 is supposed to
be the last release before switching to the 5.x branch. One can only
hope (expect?) that they'll be a tad more current then.
Actually, it's not about how current MinGW is - it does have the necessary
functions (the _aligned_malloc) function. The necessary function is only
available from XP though, and MinGW still seems to default to win2k as
baseline. Configuring with --extra-cflags=-D__MSVCRT_VERSION__=0x0700 does
not need the memalign hack.
See https://lists.libav.org/pipermail/libav-devel/2012-June/029342.html
for a discussion on the matter.
