1998-07-10 Dave Love <d.love@dl.ac.uk> * Makefile.in: Re-write build procedure mainly to honour dependencies correctly but also allow making in the build directory by configuring the relevant variables. The lib[FIU]77 subdirs do dependency checking of their objects. Stamp files dictate when to run (new) archive targets in subdirs. Some tidying of variables. Supply full set of standard targets. * configure.in: Move much of testing to new configures in subdirs. Tidy up handling of RANLIB etc. * stamp-h.in, libF77/configure.in, libI77/configure.in, libF77/configure, libI77/configure: New files. * libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in: Change in step with libf2c/Makefile.in.
