intptr_t in unistd.h

This change seems to be necessary to allow things that use some combinations
other than _GNU_SOURCE et al to compile.

2000-03-26  Roland McGrath  <>

	* posix/unistd.h (intptr_t): Conditionalize on [__USE_MISC ||
	__USE_XOPEN_EXTENDED] rather than on [__USE_UNIX98].
	We need this for the sbrk decl, which can be included without Unix98.
