Dear GCC-Developpers,

when trying to build a 8051-Cross-Compiler I get a:

    rm -f ${name}.o; \
  done

  make[1]: *** [libgcc2.a] Error 1
  make[1]: Leaving directory `/gnu/gcc-2.95.2/gcc'
  make: *** [all-gcc] Error 2


Do I have to provide the header files (stdlib.h, unistd.h, ...)?

I only want the compiler to create assembler code for the 8051. Do I
need a libgcc2 ? 
I also don´t have a archiver. I use a shell-script which determines the
asm-routines that
are needed and calls the assembler with the appropiate files to create
hex-files.

The files cccp and cc1 were already created, can I use them?


When I try to compile a simple program with the created cc1 like:

        int main(void)
        {
          int a=0;
          return 0;
        }

the cc1 crashes with:
 
 main
test1.i: In function `main':
test1.i:5: Internal compiler error in `instantiate_virtual_regs_1', at
function.c:4027
Please submit a full bug report.
