crosstool-NG Cygwin Build Fails

crosstool-NG Cygwin Build Fails

[Lusk, Timothy CCS]

The newest two versions of crosstool-NG (1.14.x and 1.15.x) no longer build correctly on Cygwin.  It fails to find libintl and nconf fails to find the folder with the ncurses sources.  It also doesn't like it if you're using the wide character version of ncurses (ncursesw), but the first two issues still occur when using the original ncurses library.  I used the following patches to get it building in Cygwin.  Just a heads up for anyone else who might run into this problem.

I can't test Cygwin, as I have no windows machine (not even a VM),
so I rely on users' testing and reports. Thank you for the heads up! :-)

For users interested in running under Cygwin, it would be nice to test
the repository from time to time, to be sure to catch breakage asap, and
not wait for the release to be out. ;-)

Would you care sending a unified diff, please? It is much easier to read:
  diff -du file-1 file-2

Ideally, you'd follow the tutorial on how to submit changes:
  docs/7 - Contributing to crosstool-NG.txt

Yann E. MORIN.

Yann,

Here is the patch as a unified diff. It's essentially just adding the libintl library, specifying the ncurses path, and changing the way ESCDELAY is set.
