Yep.
Note that if Iam not mistaken we are about 7 hours separated in time. I
followed this thread a bit passively the last weeks, anyway I saw that you
are now very actively involved in getting building on MinGW to work; while
my available time is maybe 1-2 hours each evening (but my laptop can work
all night). Tonight I got maybe 10 minutes left.

No, I started with the 32-bit MinGW stuff (to make a 32-bit Octave).
But perhaps 64-bit is a better goal on a 64-bit machine anyway.

AFAICS it is built-in somewhere deep in MinGW. There are some related
threads on this in various MinGW lists. Maybe it is related to win32api
files. Tomorrow I'll dig a bit further.

Philip

I think it pulls in the windows libraries as part of win32api

One of the machines I have been compiling on  is a Win7 machine running
mingw3 - but I haven't had any issues with it not being able to run
executables that I have noticed - In fact it has behaved the same as my XP
(32bit) machine with the same messages on not being able to find openssl etc
for postgres, qrupdate not untaring and qt complaining about needing a
-platform option :)
