[PATCH, approved]: Fixes HPUX 11 "size_t" compile problems with binutils, etc.

[Josh Martin <Josh dot Martin at abq dot sc dot philips dot com>]

This patch addresses a problem on HP-UX 11.00 when compiling packages such as 
GNU binutils, or Sleepycat Berkeley DB. Some of the HP header files (such as 
ctype.h) were defining __size_t as size_t (or std::size_t). When these files 
were included before stddef.h they were causing size_t to be left undefined, 
generating compiler errors. This patch changes these HP header files to use 
_hpux_size_t instead of __size_t, thereby bypassing the problem. This patch has 
bootstrapped successfully with gcc 3.0.1 on an hppa2.0n-hp-hpux11.00 system with 
no new regressions. The ChangeLog and then patch are as follows:

	* fixinc/inclhack.def(hpux11_size_t): Keep HP-UX headers from
	defining __size_t and leaving size_t undefined.
