X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=06c9266b0a6c3b4fb96b7a6e1ec158e2585e8c01;p=pspp

strtok_r: Move AC_LIBOBJ invocations to module description.

* m4/strtok_r.m4 (gl_FUNC_STRTOK_R): Set HAVE_STRTOK_R. Move AC_LIBOBJ
and gl_PREREQ_STRTOK_R invocations from here...
* modules/strtok_r (configure.ac): ... to here.
(Depends-on): Update conditions.
