Subject: * bootstrap (cleanup_gnulib): New function.  Use it to clean up
X-Git-Tag: v2.3b~587
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/e10a80eeacc597767cf01c0277bc3e200f498688

* bootstrap (cleanup_gnulib): New function.  Use it to clean up
gnulib when interrupted.  This fixes some race conditions and
works around some portability problems (one noted by Paul
Hilfinger).
