[Pgpool-general] pgpool-II 3.0 and getopt.h missing on SCO 5.0.7

[Edmundo Robles L.]

hi!  i tried to compile pgpool-II 3.0 beta1 on SCO 5.0.7 , but    i 
can't find  getopt.h file ,  i just  have an getopt_.h from gnulib but  
is not enough to compile it.

There is a  way to disable long options?
or
where can  i find a getopt.h file (and getopt.c to  compile. ;-) ) ??
