[gdal-dev] Link GDAL with MinGW

[Ari Jolma]

MinGW gcc generates .dll.a files, which are the link libraries, but it 
can also use the plain dll to link against.

However, when you mention gdal16.dll, it sounds like you're trying to 
link against a GDAL dll that was generated with VC. The C++ API is very 
difficult to use from such dll when you're developing with MinGW if not 
impossible. I, for one, have never succeeded. The Swig bindings use some 
C++ API, which have so far prevented me from using "an official" binary 
gdal dll for the Perl bindings for example.
