Subject: MSVC: Rebuild spiexceptions.h when out of date.
X-Git-Tag: REL_11_BETA1~1243
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9363b8b79b0f2475b5b607fe4e0aa73a86398223;p=postgresql

MSVC: Rebuild spiexceptions.h when out of date.

Also, add a warning to catch future instances of naming a nonexistent
file as a prerequisite.  Back-patch to 9.3 (all supported versions).
