Hi all, I am trying to compile Crawl under Cygwin under Windows 7. However I get the following errors when trying to use make:

CXX libunix.o
libunix.cc:24:18: warning: term.h: No such file or directory
libunix.cc:43:22: warning: langinfo.h: No such file or directory
libunix.cc:44:21: warning: termios.h: No such file or directory
libunix.cc:61:24: warning: curses.h: No such file or directory

However, langinfo.h does exist here and here:
C:\cygwin\usr\include
C:\cygwin\usr\x86_64-pc-cygwin\sys-root\usr\include

How do I tell make to look here? Or what do I need to do/install/copy/move?
