The precompiled DLL was built using MSVC and is using SEH.
The C++ EH is in there to support building the library
with the GNU compilers. The third option (ie. build with C
and no EH) perhaps shouldn't be there, although, provided
people are aware of the limitations could be useful to
someone.

Side note: the EH within the DLL should be self-contained
such that an application which uses the library can be
built as standard C without EH and not run into trouble.
At least that is what I've been assuming. I could be wrong.
