|

| 114 | # as possible we want (at least) the following:
|
|---|
| 115 | # * Allow make to be run at the top level (all-target-libf2c), at this
|
|---|
| 116 | # level, or the subdirs of this level. In the latter case we only
|
|---|
| 117 | # compile, rather than updating libg2c.a;
|
|---|
| 118 | # * A robust set of dependencies, so that we rebuild (as little as
|
|---|
| 119 | # possible) if a configuration file, g2c.h or any lib?77/*.c file
|
|---|
| 120 | # changes;
|
|---|
| 121 | # * Avoid unnecessary running of ar and ranlib;

| 122 | # * Expose parallelism where reasonable, but not as a priority.
