Why not just take the version from 2.5?
Or is there a problem with this one too and gcc2.95.3?

#ifdef SMBFS_PARANOIA
# define PARANOIA(f, a...) printk(KERN_NOTICE "%s: " f, __FUNCTION__ , ## a)
#else
# define PARANOIA(f, a...) do { ; } while(0)
#endif

etc.

Note the extra space ...

I'm just wary about the extra blank which is error prone. Otherwise
there's no problem.

I've tried to provoke this error, but been unable to; the code
works just fine even without the extra space. Can anyone
confirm if gcc-2.95.4 in Debian lacks this bug?!

Anyway, *please* can we try to avoid GCC-versioned code as much as
possible? Either we raise the required GCC-version (not possible until
the SPARC64-people become perfectly happy with gcc-3.2) or we stay at
a lower version and work around the warts.
