- When *configure* changes, plain "make" doesn't error out anymore,
telling you to remove auto/config.cache; instead, it removes it itself
and configure proceeds to completion. It may find out at the end that
config.h is unchanged, in which case only pathdef.o (and any module
whose source has changed) will be recompiled.
- Running configure (other than as part of make reconfig) doesn't add an
additional instance of -D_FORTIFY_SOURCE=1 for each run of configure
This means that after configure has changed, a plain "make" will
succeed; it isn't anymore necessary to replace it with "rm -v
src/auto/config.cache && make reconfig" (the src/ part is superfluous
when running in a shadow directory, e.g. when building several
featuresets of Vim in parallel, as I usually do; the "make reconfig"
used to be what I had to do to avoid define-flag creep).
I have not checked whether running "make reconfig" immediately after
configure has changed still runs configure twice in succession. (I will
assume it doesn't until or unless I see the opposite.)
This removes (as we say in French) a big thorn from my foot. Thanks Bram
(and Ken Takata)!
