IRIX compiler warnings/errors for 0.99.1

[Michael Callahan <callahan xmission com>]

Here's fixes for all the warnings/errors I had while compiling gtk+-0.99.1
on an SGI with the system cc compiler and CFLAGS='-fullwarn'.  I'll do
CFLAGS='-fullwarn -64' next to track down as many 64 bit warnings/errors
as I can find.

The default sgi cc compiler barfs on this empty default.  I commented
it out, but perhaps yanking it altogether or putting an empty statement
after it would be a better solution.

These are missing system includes.  Note that <string.h> is already used,
but is not defined on some older systems that have <strings.h> instead.
Perhaps this should be checked with autoconfig?

These two enumerated types have extra commas in them, not a very big deal,
but it produces a warning and isn't standard C.

The typedefs for the following functions need better type definitions.
This is because functions declared with () are indistinguishable from
a K&R prototype without the types declared.
