You're probably also using a very recent gcc.  Recent gcc had preprocessor
changes to make it more stricly comply to ISO.  This breaks a number of
files in the Linux kernel which for readability have extra space around
the ## C preprocessor paste.  I've already commited the necessary fixes
for softfp.S which is the only affected MIPS file to CVS.  There is still
a large number of other files which aren't ISO C89 compliant.   Keith
Wesolowski has made a patch for those which I'll send to Linus.
