Subject: Remove a couple other vestigial yylex() declarations.
X-Git-Tag: REL9_5_ALPHA1~535
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=9a8e23311cac14168df6644e03d533a4b07f933e;p=postgresql.git

Remove a couple other vestigial yylex() declarations.

These were workarounds for a long-gone flex bug; all supported versions
of flex emit an extern declaration as expected.
