Makefile.in (install): Don't install if $(libsubdir) is empty...

Sat Jun 13 03:46:40 1998  Craig Burley  <burley@gnu.org>
	* Makefile.in (install): Don't install if $(libsubdir)
	is empty; issue a diagnostic saying top-level Makefile
	must pass it in instead, and exit.
	* Makefile.in (g2c.h): Rename from f2c.h.
	* Makefile.in, libF77/Makefile.in, libI77/Makefile.in,
	libU77/Makefile.in: Rewrite config and var assignment
	sections to be even more minimal than before, and to
	more clearly documented what macros are expected to be
	set and to what sorts of values.  Eliminate CROSS and
	related stuff, since there's no such things as CROSS
	in egcs.  Rename GCC_FOR_TARGET to CC throughout.
	* Makefile.in (stamp-libi77, stamp-libf77, stamp-libu77):
	Eliminate CROSS.
	* configure.in: Eliminate CROSS.
	Rename libf2c.a and f2c.h to libg2c.a and g2c.h,
	normalize and simplify g77/libg2c build process:
	* Makefile.in: Remove all stuff pertaining to
	installation, cleaning, and so on.  Parent Makefile
	does all that now.  Pass F2C_H_DIR,
	G2C_H_DIR, and GCC_H_DIR, the pathnames for the
	directories containing f2c.h, g2c.h, and other
	#include files, to subdirectory Makefiles.
	(stamp-libf77, stamp-libi77, stamp-libu77):
	Don't specify `-f Makefile' anymore, it's not needed
	now that subdirectory makefile's from netlib are
	renamed to makefile.netlib in g77 source (and to
	makefile.ori by configuration process, in case they're
	still around somehow).
	(stamp-libe77): Don't make libE77 dir unless it doesn't
	exist, if it does just delete all objects in it.
	Compile using $(GCC_FOR_TARGET), not $(CC).
	(rebuilt): Remove this and all subordinate targets,
	as parent Makefile now handles all that.
	(*clean): Remove.
	* configure.in (Pad_UDread, ALWAYS_FLUSH, WANT_LEAD_0):
	Remove these and commentary to new f2c.h file.
	AC_OUTPUT g2c.h instead of f2c.h.  Remove old commentary
	regarding concatenation.
	* g2c.h.in: Rename from f2c.h.in, add appropriate
	commentary.
	* f2c.h: New file, a wrapper for g2c.h that does
	libg2c-specific stuff.
	* libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in:
	Change $(ALL_CFLAGS) to use F2C_H_DIR, G2C_H_DIR, and GCC_H_DIR
	macros.  Remove F2C_H macro, replace use with explicit
	dependencies on f2c.h and g2c.h.
	(*clean): Remove.

This directory contains the f2c library packaged for use with g77 to configure
and build automatically (in principle!) as part of the top-level configure and
make steps. This depends on the makefile and configure fragments in ../f.
g77 names this library `libg2c' to avoid conflict with existing copies
of `libf2c' on a system.
Some small changes have been made to the f2c distributions of lib[FI]77 which

be shared with f2c users), without changing the libf2c (libg2c)
