Subject: getprogname: Fix missing declaration on QNX.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=23462c65bf46f0873a0a53744a10c25644b2327d;p=thirdparty%2Fgnulib.git

getprogname: Fix missing declaration on QNX.

* lib/stdlib.in.h [@GNULIB_GETPROGNAME@ && @HAVE_SYS_PROCESS_H@]:
Include sys/process.h.
* m4/getprogname.m4 (gl_FUNC_GETPROGNAME): Check for sys/process.h.
* m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Initialize HAVE_SYS_PROCESS_H
to zero.
* modules/stdlib-h (Makefile.am): Substitute HAVE_SYS_PROCESS_H.
