Subject: Suppress 'uninitialized variable' warning emitted by some (not all)
X-Git-Tag: REL8_0_0BETA1~680
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=a90b2a035ff1bea75eda3372d513e07020293328;p=postgresql.git

Suppress 'uninitialized variable' warning emitted by some (not all)
versions of gcc.  The code is correct AFAICS, but it requires slightly
more analysis than usual to see that the variable can't be used uninitialized.
