i. Down to business I am having errors in installing wxPython on CYGWIN in

iii. In the above, Steps 1, 2, 3, 4 and 4a works like a charm, I am still
attaching the output files in case you need to refer to them.
iv. In Steps 5 i get the following warnings and error:

As Bob McGwier reported to the list on 3 Jan, there has been a major update
to Cygwin, including a switch to gcc 4.3.4. I don't know if anyone has
tried to install GNU Radio with the new version and I know that the
instructions in the wiki have not been updated for the the new version.
The immediate problem is that both winsock.h and select.h have been
included, leading to a conflict. You may be able to avoid this by editing
build-local/lib/wx/include/msw-ansi-release-2.8/wx/setup.h so that
HAVE_SYS_SELECT_H is undefined. Of course this might just be the first of
many such errors that are not easily fixed.
Another possibility is that another include file in gcc 4.3.4 is including
select.h. If that is the case, we will need to see what can be done.
It should be noted that the latest Cygwin FAQ states you can't use winsock
functions in Cygwin (even though the winsock.h header file is included in
the distribution). So they may have changed it so it just won't work.
Checking out the new Cygwin is on my list of things to do, but it probably
won't happen soon.
Please let us know what you find.
