XC32 GCC Microchip

[Giovanni <giovanni.nervi@xxxxxxxxx>]

Hi,

I trying to compile cross compiler GCC 4.5.1 released by Microchip for
targer PIC32MX.
My linux system is x86 and glibc 2.9.

This is my configure command line extracted by binary of microchip
../gcc/configure --target=pic32mx --program-prefix=xc32-
--disable-threads --disable-libmudflap --disable-libssp
--disable-libstdcxx-pch --disable-hosted-libstdcxx
--enable-sgxx-sde-multilibs --disable-threads --with-gnu-as
--with-gnu-ld --disable-sim --disable-bootstrap --enable-obsolete
--disable-__cxa_atexit --disable-libfortran --enable-languages=c
--disable-shared --with-newlib --disable-nls
--prefix=/opt/microchip/xc32 --disable-libgomp --without-headers
--disable-libffi --enable-gofast --enable-poison-system-directories
--libexecdir=/opt/microchip/xc32/pic32mx/bin --with-dwarf2
--with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic
-lm' --with-libelf --enable-lto --with-gmp --with-ppl --with-cloog
--with-bugurl=http://www.microchip.com/support

But I can't compile it.

The file stddef.h is not missing.
