Subject: Use an SQLPP command for pre-processing SQL files (#1694)
X-Git-Tag: 2.0.1~133
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=10fc02f7a5f26bcda0ef35a35be7d5d8af931b32;p=postgis

Use an SQLPP command for pre-processing SQL files (#1694)

The SQLPP command is figured at ./configure time.
It will use cpp(1) or gpp(1) if any is found in that order or
fallback to whatever CPP expands to (usually the compiler with -E)
