Aaron,

What platform are you on?  I am not sure why this is happening to you,
but not others.  However, I believe if you upgrade to the latest PROJ.4

(4.4.3 at http://www.remotesensing.org/proj) and then reconfigure and

rebuild MapServer I think you will find this goes away.  The 4.4.3 version
of PROJ.4 carefully segregates public declarations into proj_api.h and
private ones into projects.h.  The hypot() declaration in projects.h is
presumably intended to help in cases where it is missing from math.h, but
in the C++ build case (of mapogr.cpp) it conflicts with the proper C++
declaration of hypot() which includes exception information.

Let me know if the problem persists.

Best regards,
