>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
gcc version 2.95.2 19991024 (release)

/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.
