header files - either we simply include them or guard their
include using different conditionals.

Actually, checking for stdarg.h is necessary on macOS where
we need to have HAVE_STDARG_H defined for readline to use the
correct prototype for rl_message.

See commit 9ea3424a178 for more context.

Facepalm. This is what I was afraid of - that a header file we use will 
depend on autotools HAVE_ prefix. Let me see if I can fix this.
