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

 121 # the dependency) and then (perhaps) builds multilibs.
