Subject: [PATCH] configure: fix implicit function declarations
Import fedora patch:
https://src.fedoraproject.org/rpms/grace/blob/rawhide/f/grace-configure-c99-1.patch
Do not call the XmRegisterConverters function because current Motif
does not declare it (but still exports it). With this call, the
result of this configure check depends on whether the compiler
supports implicit function declarations or not.
Additionally add missing includes to various checks that lacked them.
Florian's patch moved from exit to return, but adding the includes is
shorter.
