[Kaveh R. Ghazi]

Snapshot:		CVS checkout (19980519)
Platform:		hppa1.1-hp-hpux9.01
Stage1 compiler:	cc
Assembler:		GAS-970915
Linker:			native
BOOT_CFLAGS:		none


	I get the following error in the libiberty directory during
bootstrap:

 > cc -c -DHAVE_CONFIG_H -g -I. -I./../include  getpagesize.c
 > cc: "getpagesize.c", line 67: error 1588: "_SC_PAGESIZE" undefined.
 > make[1]: *** [getpagesize.o] Error 1

	I fixed it with the following patch.  Is it okay to install?

	* configure.in (AC_CHECK_HEADERS): Check also for <unistd.h>.

	* getpagesize.c: Don't include <unistd.h> based on HAVE_SYSCONF,
	instead base it on HAVE_UNISTD_H.  Only use `sysconf(_SC_PAGESIZE)'
	if both HAVE_SYSCONF and _SC_PAGESIZE are defined.
