".dll.a": well, that's the fact.
I had terrible problems in compiling apps which link to libpq.a, which
actually is libtool problem. it's has very very low urgency.

invasiveness: see the libpq_a patch.
I wonder why you link all clients statically. with a libpq macro you
could decide to which version (shared or static) you want to link against.

arguments accepted.
though the probe for cygwin at 100 causes it NOT to fail.
this is actually a more severe problem.
It'll stay in my private patches archive.
