Thanks, I'll look in that direction...
Next question is where can I find an official Emacs 64-bit build?
Went to the FAQ, read it at
(https://www.gnu.org/software/emacs/manual/html_node/efaq-w32/Downloading.html)
it says it should be on the ftp site and there would be both a 32 and
64 bit versions but apparently there is only one of them, the 32
bit.... which I mistakenly took for the 64 bit. This probably
explains....
Google a bit further, and it appears that some guy/team publishes a 64
bit build on sourceforge.
http://sourceforge.net/projects/emacsbinw64/ but it has nothing
official and it evolves along with the most recent sources apparently.
Just now found
https://lists.gnu.org/archive/html/bug-gnu-emacs/2015-06/msg00729.html....
discussing this issue :-)
BTW, I'll also give a try at the cygwin emacs build.
I'll also look at building Emacs from source for x64....
Conclusion:
- I now have a version (25.xx) that works with cygwin64 bash....
- FAQ still a somewhat misleading
- I'll have a look at building Emacs from source.... and see how to
share the results.
Thanks anyway to all.
