[postgis-users] Strange error

[strk at refractions.net]

Does it happen after a make clean as well ?
The problem is that there are 3 implementation for centroid().
Which one is used is decided upon the compile-time defines:
	USE_GEOS
	USE_JTS
If you changed those vars after a build, you'll need a make clean
to force re-evaluation of them.

If the problem persists it might be a mis-support for your
preprocessor, can you provide version of it ?
