Hi folks,

With the TIOCGWINSZ support to take care of detecting the # of rows and 
columns, I encountered another problem.

ncurses/tty/lib_tstp.c now fails with DJGPP to compile because SIGWINCH is 
used.  config.priv.h turns off USE_SIGWINCH if HAVE_SIZECHANGE hasn't been 
defined by the configure script. 

A quick fix to get ncurses to build is to turn off USE_SIGWINCH if 
SIGWINCH isn't defined.

  #define USE_SIGTSTP 0

+ #undef USE_SIGWINCH
+ #endif

  /*
   * Note: This code is fragile!  Its problem is that different OSs
   * handle restart of system calls interrupted by signals differently.

But I think a better fix would be change the configure script to not have 
USE_SIGWINCH defined in curses.priv.h if SIGWINCH isn't defined.

I forgot to add in the last note that DJGPP can indeed run configure 
scripts (Bash 2.03 and above have been ported and all essential GNU 
tools).
