Well, autoconf cannot check for everything (even if we would try to do that,
there will be always systems which are not supported out of the box). If you
want to try to add support for your system, go ahead. I really cannot think of
when and why we would need to link with -lmygcc or what libs.a is.

If you just want to use PHP on your system:

LIBS="-lmygcc -ls" LDFLAGS=-L/prog/mysql/lib ./configure [other flags]
