I tried to compile Mapserver 6.2 with proj 4.7. I'm having a problem with a
function called "pj_clear_initcache"
As far as I can see, this function was introduced in proj 4.8 and is not
part of proj 4.7.
In Mapserver 6.2 maputil.c has code
where Mapserver 6.0 used.
I changed to
but didn't test this with proj4.8
fix proj version check (#4526)
typo in the check for proj's lookup cache existence
