Subject: [committed] hppa-hpux11: New include fix for alloca.h
Authentication-results: sourceware.org; auth=none

The alloca.h header on hppa-hpux needs to include sys/stdsyms.h to define _PROTOTYPES, etc.
It was assumed that stddef.h would include sys/stdsyms.h.  However, the HP version of stddef.h is
now replaced by a GCC version and it doesn't include sys/stdsyms.h. 

The attached change modifies alloca.h to explicitly include sys/stdsyms.h if it hasn't been included
previously.  This fixes the libgomp.oacc-c-c++-common/loop-dim-default.c test case.

Tested on hppa64-hp-hpux11.11.  Committed to trunk.
