Subject: build: don't require src/bison during bootstrap.
X-Git-Tag: v2.7.90~693
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/a7ddefd1c21e3bd3a90cb0a18bb67e0e2f2408c8

build: don't require src/bison during bootstrap.

Suggested by Eric Blake at
<http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00003.html>.
* bootstrap.conf (bootstrap_epilogue): New function to make sure
src/parse-gram.[ch] are stamped later than src/parse-gram.y.
(cherry picked from commit b733bcd00e6fc8db45c86dc289938a28c1bf72d8)
