30 * Known contributors to this file:
31 * Ron Koenderink, 2007
32 * Markus Armbruster, 2007-2009
36 * We can provide POSIX headers that don't exist in Windows, but we
37 * can't augment existing headers. Some stuff that should be in such
38 * headers ends up here, and some in w32misc.h. Can't be helped.
45 * We override system functions by defining them as macros. This
46 * breaks if the system's declaration is included later. Include them
47 * here. Major name space pollution, can't be helped.
