Using `fork' will be deadly for dos/windows. Please try to avoid it
if possible.  I would like to suggest two alternatives at least for
dos/djgpp:

- the use of popen/pclose.
- the use of posix_spawn* family of functions.

Information about posix_spawn* family of functions are available
from http://www.opengroup.org/

Both alternatives are available for DJGPP and would make
the bison code be compilable out-of-the-box.
