[Vortex] MinGW & vortex lib problems

lib.exe is a windows platform specific tool bundle with Microsoft
compilers (at least that's the source we use to get it; visual studio
2005 express). Its main function is to produce a windows import library
from a export file (a .def file). 

If you are using mingw for your own production you won't need this since
gcc has the ability to links against dlls using its direct reference.
This is only used to produced the windows installer.

You shouldn't get these errors since those symbols are included in the
msys and mingw distribution. No clue at this point..:-? Looks like your
mingw environment needs more configuration. I would suggest to check all
variables inside Makefile.win files, and if a minimal main.c file using
those symbols can create an executable using gcc....

Ok. I'll take into account this...

Ok. Makes sense.

Current distribution includes a src/Makefile.win file that do not have
by default activated sasl and tls support. 

Only internal features (like tunnel and xml-rpc profile) are activated
by default. See: $(OPENSSL_FLAGS), $(OPENSSL_LIBS), $(GSASL_FLAGS) and
$(GSASL_LIBS). Take a look at [1]. Its the main makefile.win file used,
and provides some examples about previous variables.

Cheers!
