More Linux, Mapserver and ECW SDK

[James Browne]

First, thanks for bug fixes and past help.

I almost have the ecwsdk built, with patches and fixes, but I can't get libNCSEcw to link to libNCSUtil. All the *.o are there for both and the paths work, but I get:
undefined reference to NCSMutexTryBegin
and several each of
undefined reference to CNCSEvent::CNCSEvent[in-charge](bool, bool, char*)
and
undefined reference to CNCSEvent::~CNCSEvent[in-charge]()

even though mutex.c and NCSEvent.cpp compile and link into libNCSUtil.

Any hints?
