>Environment:
i686 running cygwin (dll 1.1.4) under Win2K; compiler build is cross compiler for powerpc-elf
>Description:
gcc produces assembly but doesn't pass the assembly file to as.  My guess is that a <CR> is getting in the way:

Reading specs from /usr/local/lib/gcc-lib/ppc-elf/2.95.2/specs

 /usr/local/ppc-elf/bin/as.exe 

Assembler messages:
Error: Can't open ^M for reading.
^M: No such file or directory

>How-To-Repeat:
Build binutils-2.10: ../binutils-2.10/configure --target=ppc-elf --program-prefix=ppc-elf- --with-newlib --with-headers=/usr/include --enable-languages=c,c++ 

Build gcc-2.95.2: ../gcc-2.95.2/configure <same options>

Start building newlib-1.8.2 (same options).  The first compile (.../newlib-1.8.2/newlib/libc/stdlib/__adjust.c) will fail with "Assembler messages" like above.
>Fix:
I'm assuming that the fix is to ensure the script (?) doesn't have a '\r' before '\n'.  This is default windows behaviour, and needs to be explicitly disabled by opening files as binary using fopen(output_file, wb) or _setmode(output_file, _O_BINARY).  The problem is, I don't know what generates the script, or alternatively, who reads it.
