  88 # The logic here is partly dictated by the desire to keep the lib?77
  89 # subdirs for compatibility with the Netlib version and because libU77
  90 # has a different copyright; then the libe77 bit (EXTERNALly-callable
  91 # versions) is funny.  Given that, as well as keeping things as simple
  92 # as possible we want (at least) the following:
  93 #  * Allow make to be run at the top level (all-target-libf2c), at this
  94 #    level, or the subdirs of this level.  In the latter case we only
  95 #    compile, rather than updating libg2c.a;
  96 #  * A robust set of dependencies, so that we rebuild (as little as
  97 #    possible) if a configuration file, g2c.h or any lib?77/*.c file
  98 #    changes;
  99 #  * Avoid unnecessary running of ar and ranlib;
 100 #  * Expose parallelism where reasonable, but not as a priority.
 101
 102 # The intended top-level target here does a non-multilib build (via
 103 # the dependency) and then (perhaps) builds multilibs.

 112 # update stamp files (see the subdir makefiles) which the $(LIBG2C)
 113 # target checks in the sub make to decide whether to run ar/ranlib.
 114 # (Probably only one stamp file is really needed.)  The stamp files
 115 # s-lib[fiu]77 are intentionally not targets, since we're only meant
 116 # to come in at the level of this target.  The [fiu]77 targets always
 117 # invoke sub makes to check dependencies in the subdirs, else we'd
 118 # have to maintain them at this level; we live with the overhead of
 119 # some recursive makes which may do nothing.
