(a) it IS unusual to #include both

(b) both cygwin (the package, containing the dll) and ncurses (by 
default) provide a termcap.h file.  I assume that curses.h -- which on 
cygwin is from ncurses -- and ncurses' termcap.h would both agree. 
However, cygwin's termcap.h and ncurses' termcap.h are different. 
Besides, any rational package management system allows each file to ONLY 
be provided by one package -- or the packages must be marked as conflicting.

We can't very well have cygwin's 'ncurses' package conflict with 
cygwin's 'cygwin' package.

So, when I put together the ncurses packages, I rename ncurses' 
termcap.h to avoid conflicts. Because (see (a), above) it is unusual to 
#include both.  FWIW, "termcapn.h" lives in /usr/include/ncurses/, and 
unlike some of the other headers in that subdir, the postinstall script 
does NOT create a symlink to it from /usr/include/.

I suppose one solution would be for me to stop renaming the header file, 
and then you could add -I/usr/include/ncurses/ to your CFLAGS.  That 
way, you'd get the ncurses-derived termcap.h which would, presumably, 
not conflict with the ncurses-derived curses.h...
