Hmm, yes. I wasn't sure but as I recall I ticked those boxes yes. I told 
you my notes weren't thorough!

I mentioned it after pdcurses - don't recall there being any notable 
problems with it hence the briefness of the mention!

I couldn't find flex on the Mingw site. Maybe I was blind. Is it there? 
Yes, just putting the flex.exe in the mingw bin directory worked fine for 
me.

Ah OK. I think I hacked about with that a little bit come to think of it. 
Just put it where it's looking for it ;)

Good point. I should think there is only that one file affected by that 
though. Shared files needed by PROJ and GDAL are generally included with 
GRASS. See earlier discussions on the mailing list today about that EPSG 
file.

Just make sure c:\forgrass\lib is in your PATH before you start compiling 
and it should be fine. I copy them after compilation just to have 
everything self-contained for distributing it to others. As long as the 
DLLs are on your system and in the PATH everything should work.

Also you need to change man/Makefile so it doesn't convert the HTML pages 
to man. The Makefile should be conditionalised so this is dependent on 
Perl being installed. Will look at it later.

Thanks a lot for testing this.
