include unistd.h if present, for `rmdir'.
* physmem.m4 (gl_SYS__SYSTEM_CONFIGURATION): Avoid unused
variables.
* putenv.m4 (gl_FUNC_PUTENV): Rewrite using AC_RUN_IFELSE, and
in the process include standard headers for prototypes.
* readutmp.m4 (gl_READUTMP): Require AC_GNU_SOURCE, so utmpxname
gets declared on GNU/Linux.
