X-Git-Tag: 2.0.0alpha4~26
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1de0d3d8ae55b3ccf1b73151ed4b8e668d17ce12;p=postgis

Force generation of an svnrevision.h file when building in a repo and the svn executable is available.
Ensure that when building a tarball with make_dist.sh the revision is read from the tag in the remote svn repository.
This should cover both development and distribution cases.
