PATCH: Fixes "size_t" compile problems with binutils, etc. on HPUX 11.00

[Josh Martin]

Made changes to gcc/ginclude/stddef.h to correct compile problem causing size_t 
to be undefined on HPUX 11.00 when compiling such packages as GNU binutils and 
Sleepycat Berkeley Database. Certain HPUX 11.00 system headers were defining 
__size_t as size_t, thus causing the definition of size_t to be skipped in the 
stddef.h header file. Ideally, a hack should be added to fixincludes which 
removes these defines from the system headers, but I don't know if this will 
break any of the other system headers. This patch successfully bootstrapped on a 
hppa2.0n-hp-hpux11.00

Patch follows, and then ChangeLog:

        * gcc/ginclude/stddef.h (__size_t): Check for HPUX and undefine
        __size_t to allow size_t to be defined.
