Subject: Suppress FLEX_NO_BACKUP check for psqlscanslash.l.
X-Git-Tag: REL9_6_BETA1~441
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a3e39f83632935911bc159154a33e89495f4a676;p=thirdparty%2Fpostgresql.git

Suppress FLEX_NO_BACKUP check for psqlscanslash.l.

The existing infrastructure for FLEX_NO_BACKUP doesn't work reliably
when two lexers are built in parallel in the same directory.  We can
probably fix that, but as a short-term workaround, just don't make
the check for psqlscanslash.l.

Per buildfarm.
