 I have no idea if just replying to this works, with all those CC's, but I
 hope for the best.

 That is my fault for not being precise enough in my bug report, sorry.
 
 The problem is that gcc calls the preprocessor with this ordering when
 compiling an assembler file (foo.S) with the -std=gnu99 option.
 
 Try "echo \# foo > foo.S" and "gcc -std=gnu99 -o foo foo.S", this triggers
 the bug.  -v shows that gcc passes -std=gnu99 to cpp when preprocessing the
 file.
 
 Thanks,
 Marcus
