# The logic here is partly dictated by the desire to keep the lib?77
# subdirs for compatibility with the Netlib version and because libU77
# has a different copyright; then the libe77 bit (EXTERNALly-callable
# versions) is funny. Given that, as well as keeping things as simple
# as possible we want (at least) the following:
# * Allow make to be run at the top level (all-target-libf2c), at this
# level, or the subdirs of this level. In the latter case we only
# compile, rather than updating libg2c.a;
# * A robust set of dependencies, so that we rebuild (as little as
# possible) if a configuration file, g2c.h or any lib?77/*.c file
# changes;
# * Avoid unnecessary running of ar and ranlib;
# * Expose parallelism where reasonable, but not as a priority.
# The intended top-level target here does a non-multilib build (via
# the dependency) and then (perhaps) builds multilibs.

# `all-unilib' is the overall target in the absence of multilibs,
# meant to be invoked via multi-do for multilibs.
# Its dependencies can be satisfied in parallel. The [fiu]77 targets
# update stamp files (see the subdir makefiles) which the $(LIBG2C)
# target checks in the sub make to decide whether to run ar/ranlib.
# (Probably only one stamp file is really needed.) The stamp files
# s-lib[fiu]77 are intentionally not targets, since we're only meant
# to come in at the level of this target. The [fiu]77 targets always
# invoke sub makes to check dependencies in the subdirs, else we'd
# have to maintain them at this level; we live with the overhead of
# some recursive makes which may do nothing.
