These patches to bison 1.19 remove all references to the macro USG from the
bison source code.  This macro is obsolete, and usage of it has been
inconsistent.  It has been replaced by two specific checks, for <string.h>
and <memory.h>.   The bulk of these patches are changes to the configure
script, which should be regenerated from configure.in anyway.

Yours for cleaner code.....

+ 
+ 	* configure.in: added a check for <memory.h>
+ 
+ 	* conflicts.c: use HAVE_MEMORY_H instead of USG for <memory.h>,
+ 	remove test for USG by <alloca.h>
+ 
+ 	* getopt.c: remove test for USG for <alloca.h>
+ 
+ 	* system.h: rework so that testing for USG is no longer needed
