I'm having a heck of a time recreating the issue in a simple test
case.  What I see happening with Emerge is that the C++ mangled name
seems to be mismatched between the export and the import but only in
certain circumstances.  For example:

../.objs/Release/emergeHotkeys/Settings.o:Settings.cpp:(.text+0x504):
undefined reference to
`__imp___ZN12BaseSettings8IOHelperC1EP12TiXmlElement'

However, looking at the symbols in the emergeBaseClasses import library:

$ nm bin/libemergeBaseClasses.a | grep IOHelper
...
00000000 I __imp___ZN12BaseSettings8IOHelperC2EP12TiXmlElement

I have no idea C2EP12TiXmlElement (in the export) becomes
C1EP12TiXmlElement (in the import).  I haven't been able to recreate
it as of yet in a simple case (one exe, one dll), but I'll keep
trying.

Cheers!

Chris
