texi2pod.pl: Handle @option and @env.
contrib:
* texi2pod.pl: Handle @option and @env.
gcc:
* configure.in: Require at least texinfo 4.0. Check for whether
Pod::Man is sufficiently recent to regenerate GCC manpages.
* configure: Regenerate.
* Makefile.in (TEXI2POD): Call perl explicitly rather than relying
on #!.
(GENERATED_MANPAGES): Define.
(generated-manpages): New target. Depend on cpp.1 as well as
gcov.1.
(install-man): Depend on $(GENERATED_MANPAGES) (defined by
configure to generated-manpages or empty) rather than on the
manpages directly. Remove execute permission from installed
gcov.1 as well as cpp.1.
* cpp.1, gcov.1: Regenerate.
