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

128 # update stamp files (object file lists, actually, see the subdir

130 # s-lib[fiu]77 are intentionally not targets, since we're only meant

134 # some recursive makes which may do nothing.
