I'm trying to build a powerpc/arm/mips-elf toolchain hosted on Windows using Linux as the build machine but I'm running into the following error: --- cd /tmp/gccbuild/build/gcc/mips-elf/soft-float/libgcc mips-elf-gcc -v -nostdinc -isystem /tmp/gccbuild/build/gcc/./gcc/include -B/tmp/gccbuild/build/gcc/mips-elf/soft-float/newlib/ -isystem /tmp/gccbuild/build/gcc/mips-elf/soft-float/newlib/targ-include -isystem /tmp/gccbuild/src/gcc/newlib/libc/include -B/tmp/gccbuild/build/gcc/mips-elf/soft-float/libgloss/mips -L/tmp/gccbuild/build/gcc/mips-elf/soft-float/libgloss/libnosys -L/tmp/gccbuild/src/gcc/libgloss/mips -msoft-float -O2 -g -g -O2 -O2 -O2 -g -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -G 0 -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../../.././gcc -I/tmp/gccbuild/src/gcc/libgcc -I/tmp/gccbuild/src/gcc/libgcc/. -I/tmp/gccbuild/src/gcc/libgcc/../gcc -I/tmp/gccbuild/src/gcc/libgcc/../include -DHAVE_CC_TLS -o _fixunssfsi.o -MT _fixunssfsi.o -MD -MP -MF _fixunssfsi.dep -DL_fixunssfsi -c /tmp/gccbuild/src/gcc/libgcc/../gcc/libgcc2.c \ -DLIBGCC2_UNITS_PER_WORD=4 => Using built-in specs.

Added it to the path. - ran script below - gcc 4.3.2, gmp 4.3.2, mpfr 2.3.1, newlib CVS HEAD(>16.0), binutils 2.18 - I messed around with trying to add the right include files without too much luck. The problem is that I don't really know what's wrong... - tried GCC CVS HEAD - tried some other targets without luck, same result. (arm-elf, powerpc-eabi). - Once I have this working for Windows, I'll be able to build Cygwin hosted toolchains in the same fashion.
