compiling on IRIX

[Geoffrey Simms]

I'm having trouble compiling global on an SGI Origin 200, running IRIX 6.5.

The header libdb/db.h in the global distribution has some incompatibility 
with the IRIX system types when it does "typedef u_int32_t pgno_t;" since 
pgno_t has already been declared as "long" in /usr/include/sys/types.h. 

I tried changing all inlcusions of "db.h" to <db.h> and even 
"/usr/include/db.h" but then after compiling, the gtags program didn't 
work. It parsed all of the files (I watched its progress with -v on) and 
then after the last file it freezes.
