I must admit I didn't know I could set that variable in the t-* file.
But I think it does the wrong thing, it appears to override only the
test in the generated cegcc/src/build-mingw32ce/gcc/gcc/Makefile :
if $(LIMITS_H_TEST) ; then \
cat $(srcdir)/limitx.h $(srcdir)/glimits.h
$(srcdir)/limity.h > tmp-xlimits.h; \
else \
cat $(srcdir)/glimits.h > tmp-xlimits.h; \
fi; \
$(mkinstalldirs) $${fix_dir}; \
chmod a+rx $${fix_dir} || true; \
rm -f $${fix_dir}/limits.h; \
mv tmp-xlimits.h $${fix_dir}/limits.h; \
chmod a+r $${fix_dir}/limits.h; \
so all it appears to influence is whether glimits.h is surrounded by
limitx.h and limity.h or not.
What we need here is no limits.h coming from gcc because it already
comes from our src/mingw/include .
Inspired on all that, how does the patch attached look ?
It should be the more fundamental take on the problem.
