Subject: MSVC: Rebuild spiexceptions.h when out of date.
X-Git-Tag: REL9_6_7~75
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ad083e4ede522548045989995b36f3fe2d16a984;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MSVC: Rebuild spiexceptions.h when out of date.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).
