badly punctuated parameter list in `#define' (2.4.3-ac5 and 2.4.4 -pre2)

[Wayne.Brown@altec.com]

When compiling 2.4.3-ac5 (and also 2.4.4-pre2) I get this:

/usr/src/linux-2.4.3-ac5/include/asm/rwsem.h:26: badly punctuated parameter list
 in `#define'

This appears to be due to some code in rwsem.h that is written for a different
version of gcc. (I'm still using gcc-2.91.66 as specified in
Documentation/Changes.)  It works for me if I replace it with the code in the
section labeled /* old gcc */.  Here's a patch to do that:
