it's for mapping to native dll stuff.

yep. but we're on win32.

because I also had to edit the various scripts, like
ncurses/tinfo/MKnames.awk which defines macros based on other macros:
 #define DCL(it) NCURSES_EXPORT_VAR(IT) it[]
However, DCL(it) is used in the file which **defines** the variables,
not merely in the files which **declare** the variables. So, you can't
use 'extern' there.
Actually, I originally DID define NCURSES_EXPORT... with 'extern' but
had to remove it (and put it BACK into all the source files from which
I'd removed it) for this reason.

Yes, I had to munge up lots of the scripts to get things right. *That*
is only part I'm worried about whether it still works on Linux &etc. (I
*think* it should be okay -- since, in this context,
Linux=Cygwin_static_build)
Scripts affected:
ncurses/tty/MKexpanded.sh
ncurses/tty/MKnames.awk
ncurses/tty/MKfallback.sh
ncurses/tty/MKcaptab.awk
ncurses/base/MKunctrl.awk
ncurses/base/MKlib_gen.sh
ncurses/base/MKkeyname.awk
