The code in question in glib looks like this:
static gpointer
allocator_memalign (gsize alignment,
gsize memsize)
{
gpointer aligned_memory = NULL;
gint err = ENOMEM;
#if HAVE_COMPLIANT_POSIX_MEMALIGN
err = posix_memalign (&aligned_memory, alignment, memsize);
#elif HAVE_MEMALIGN
errno = 0;
aligned_memory = memalign (alignment, memsize);
err = errno;
#elif HAVE_VALLOC
errno = 0;
aligned_memory = valloc (memsize);
err = errno;
#else
/* simplistic non-freeing page allocator */
...
#endif
The #else part only calls malloc, and I assumed that it works on cygwin. It
would be a small thing to figure out which part is used on cygwin if the
config.h was available.

Yes, checking config.h for glib.
