+# 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.

+# (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
