If a package uses the zero- or one-argument form of AC_INIT, the warning for
present-but-not-usable headers looks like this:
configure: WARNING: foo.h: present but cannot be compiled
configure: WARNING: foo.h: check for missing prerequisite headers?
configure: WARNING: foo.h: see the Autoconf documentation
configure: WARNING: foo.h: section "Present But Cannot Be Compiled"
configure: WARNING: foo.h: proceeding with the preprocessor's result
configure: WARNING: foo.h: in the future, the compiler will take precedence
configure: WARNING: ## ------------------------------------------ ##
configure: WARNING: ## Report this to the AC_PACKAGE_NAME lists. ##
configure: WARNING: ## ------------------------------------------ ##
(With the rare two-argument form of AC_INIT, one would see the package name
above.)
This patch makes `configure' omit the report request when we have no
bug report address to provide. Ok?

* lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
report request when we have no AC_PACKAGE_BUGREPORT.
