[ECOS] Building dl_edb7xxx for cygwin?

["Lewin A.R.W. Edwards" <larwe at larwe dot com>]

Since I now have to run in WinNT, I can't use the Cirrus flash downloader 
app to get my ROM-built eCos app onto my board. What do I need to do in 
order to get Red Hat's port to build inside cygwin? If I just try "make" I 
get the following:

gcc    -c -o dl_edb7xxx.o dl_edb7xxx.c
dl_edb7xxx.c: In function `main':
dl_edb7xxx.c:64: warning: return type of `main' is not `int'
gcc    -c -o io.o io.c
io.c: In function `CharReady':
io.c:139: `FIONREAD' undeclared (first use in this function)
io.c:139: (Each undeclared identifier is reported only once
io.c:139: for each function it appears in.)
make: *** [io.o] Error 1
