// fixups.h :
// This file is included at the end of the generated config.h, for repairing things
// the configure script got wrong. Because this does happen now and then.
//
// This header is intentionally not wrapped with the usual #ifndef/#define/#endif
// since config.h itself doesn't do that, and we need to be inclded right after
// it each time it's included.

// Cross compiling to powerpc-wrs-vxworks from linux amd64, observed that
// AC_CHECK_FUNC defines HAVE_xxx for every checked function, including
// ones that don't and can't exist like fork() & symlink(), and others that
// could at least optionally exist, but don't in my cross compiler, like socket().
