Description of problem:

When invoked without specifying word size (-m32 or -m64), gcc appears to default to compiling 64-bit code and then invoking the assembler in 32-bit mode.

Version-Release number of selected component (if applicable):

binutils-2.19.51.0.14-3.fc11.ppc
gcc-4.4.1-2.fc11.ppc
gcc-debuginfo-4.4.1-2.fc11.ppc
libgcc-4.4.1-2.fc11.ppc
libgcc-4.4.1-2.fc11.ppc64

How reproducible:

Compile any C source file.
 
Actual results:

[user@localhost ~]$ gcc hello.c
/tmp/ccYn3Uv7.s: Assembler messages:
/tmp/ccYn3Uv7.s:17: Error: junk at end of line, first unrecognized character is `@'
/tmp/ccYn3Uv7.s:29: Error: syntax error; found `@' but expected `('
/tmp/ccYn3Uv7.s:29: Error: junk at end of line: `@toc(2)'
[user@localhost ~]$ 

Expected results:

[user@localhost ~]$ gcc hello.c
[user@localhost ~]$ 

Additional info:

The machine in question is a Mac Xserve G5. Originally, the ppc64-architecture packages for GCC and binutils were installed; later, the 64-bit packages were removed and the 32-bit packages were installed. A machine installed from scratch with only the 32-bit packages works correctly, making me suspect a package configuration bug of some sort.
