The problem is with using stdint.h integer types without checking if
they are actually
available. I have posted a fix for this already that needs to be
reviewed. Along with
some other fixes for similar target OS dependent bugs. Patch is here:
http://gcc.gnu.org/ml/gcc-patches/2006-02/msg00032.html
(and this is PR26050).
After running autoconf, it fails a bit differently. Output below my
signature.
But something doesn't seem right. *-rtems* and other newlib targets
have a stdint.h.
Shouldn't libgcc-math be including the newlib cflags and possibly
$(LIBGCC2_INCLUDES) when built? I included LIBGCC2_INCLUDES because
that is where gcc/config/t-rtems adds
the rtems specific newlib include directory.
