As for the postgres libraries, one of the problems was the name of the
library itself, pq.dll and a second problem is that ./configure assumes both
lib and include are sub-dirs of a common directory, which is not the case in
cygwin: the lib (pq.dll) is /bin and the header (libpq-fe.h) is in
/usr/include/.

See bellow the modifications I made in my ./configure file. They were
working 1 month ago but after returning from holidays I had severe problems
with my cygwin install and finally I had to reinstall. I restarted again,
but I've not yet reconfigured, make, etc. (each of these operations take
from 15 to 30 mn in my computer)

After, a successful compilation, the testing program
(./testing/gda-test.exe) had problems with the provider api (accessing the
directory for the postgres provider). That's were I interrupted my work on
trying libgda+postgres in cygwin.

I managed to do some more debugging but I have a different behavior when
running gdb!! The client api doesn't work, again with file/directory access
problems. The g_file_get_contents function was not able to open my config
file (I had no source code for the glib so I could not step it to see the
exact problem).

The name for the config file looked correct
(\\home\\fmartins\\.libgda\\config). Maybe some issue with back and forward
slashes, but I had to stop work on it. Hopefully, I'll restart tomorrow.

HTH,
Fernando
