 109 # The logic here is partly dictated by the desire to keep the lib?77
 110 # subdirs for compatibility with the Netlib version and because libU77
 111 # has a different copyright; then the libe77 bit (EXTERNALly-callable
 112 # versions) is funny.  Given that, as well as keeping things as simple
 113 # as possible we want (at least) the following:
 114 #  * Allow make to be run at the top level (all-target-libf2c), at this
 115 #    level, or the subdirs of this level.  In the latter case we only
 116 #    compile, rather than updating libg2c.a;
 117 #  * A robust set of dependencies, so that we rebuild (as little as
 118 #    possible) if a configuration file, g2c.h or any lib?77/*.c file
 119 #    changes;
 120 #  * Avoid unnecessary running of ar and ranlib;
 121 #  * Expose parallelism where reasonable, but not as a priority.
 122
 123 # The intended top-level target here does a non-multilib build (via
 124 # the dependency) and then (perhaps) builds multilibs.
