You're welcome to file a bug report if you like, but I don't consider 
this worth of one myself.

Oh.  A gcc bug report.  I really should read my mail more carefully :)

I was considering that, bug I didn't have time to research the problem 
further to see if it was really a bug or something else was going on...

I investigated this and have reported a bug:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28437

In summary, gcc 4.1.2 seems to ignore all but the last -fno-builtin-* 
flag out of many...

$ cat b.c
int iswalpha(unsigned short);
$ gcc -fno-builtin-iswalpha -c b.c
$ gcc -fno-builtin-iswalpha -fno-builtin-iswalnum -c b.c
b.c:1: warning: conflicting types for built-in function ‘iswalpha’
