GCC 4.8.0 does not compile for DJGPP
I am trying to build a cross-compiler for DJGPP running on my Ubuntu 12.10 box. #../gcc-4.8.0/configure --prefix= --target=i586-pc-msdosdjgpp #make [...] g++ -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -I. -I. -I../../gcc-4.8.0/gcc -I../../gcc-4.8.0/gcc/. -I../../gcc-4.8.0/gcc/../include -I../../gcc-4.8.0/gcc/../libcpp/include -I../../gcc-4.8.0/gcc/../libdecnumber -I../../gcc-4.8.0/gcc/../libdecnumber/dpd -I../libdecnumber -I../../gcc-4.8.0/gcc/../libbacktrace \ ../../gcc-4.8.0/gcc/config/i386/i386.c -o i386.o ../../gcc-4.8.0/gcc/config/i386/i386.c: In function ‘void ix86_code_end()’: ../../gcc-4.8.0/gcc/config/i386/i386.c:8650:55: error: ‘ASM_DECLARE_FUNCTION_NAME’ was not declared in this scope When doing the same with older versions of GCC, it was just a warning warning: implicit declaration of function ‘ASM_DECLARE_FUNCTION_NAME’ [-Wimplicit-function-declaration] Note that older versions of GCC used gcc instead of g++ Is there something wrong in GCC, or in what I am doing?

I downloaded beta/v2gnu/gcc480s.zip from a mirror, and that compiles. And, indeed, the file gcc/config/i386/djgpp.h is different from the one in the official gcc-4.8.0.tar.bz2, meaning that some DJGPP patches are not present upstream.
