Patch to enable warning flag use in libf2c

[Kaveh R. Ghazi]

This patch enables warnings flags in libf2c.  (So far I'm only adding
-W -Wall to keep the noise down, but once I cleanup the code a bit I
can work on adding more stringent warning flags.)

Tested on sparc-sun-solaris2.7 by rebuilding libf2c, okay to install?

		Thanks,

	* libF77/Makefile.in (ALL_CFLAGS): Likewise.
