Hi Stephen,

This is exactly the same problem experienced on MingW with the
DLL_EXPORT stubs causing the inlines to be defined twice at link time.
There is already a fix for this in the current source code for MingW, so
in theory all we have to do is expand the check to suppress the
duplicates when compiling with cygwin GCC as well as MingW.

Please try the attached patch to see if will allow you to compile on
cygwin - I've confirmed that the changes still allow GEOS to compile on
MingW without any problems.


HTH,

Mark.
