There's no `ualarm' in DJGPP.  However, since `ualarm' is just a
simplified interface to `setitimer', which *is* supported by DJGPP,
you could just use `setitimer' instead.

Note that `setitimer' works in the standard DOS 55-ms granularity,
since the machine clock is not sped up.

Also note that signal delivery in DJGPP is delayed when the program is
in real mode.  See the documentation of the library functiuon `signal'
for more details about this.
