 Which one ?
 Since  i  wrote  my  first  version  i remember only two topics about
spawn():
 1.  Failure  to compile Cygwin library - appeared to be PATH issue, i
have fixed this.
 2.   gcc  error:  "spawn:  no  such  file  or  directory"  -  it  was
installation problem, not a bug.

 By  the  way, breaking spawn() would break very important things like
gcc  and perl, because they use it to run subprocesses.

 Heh...  Okay,  two  against  one plus one neutral, i have to retreat.
Okay,  i'll  redo  this using environment variable, this is IMHO still
more reliable (some makefiles can be badly written, some build systems
employ shell scripts which run "make" with hardcoded options, etc).
 I  still think that compile-time option would be better. If something
breaks,  you  at  least can quickly disable it. But...
