* 11-20-89 GJF Fixed copyright, alignment. Added const to arg types
* for pathname and argv.
* 03-08-90 GJF Replace _LOAD_DS with _CALLTYPE1 and added #include
* <cruntime.h>.
* 07-24-90 SBM Removed redundant includes, replaced <assertm.h> by

*int _spawnv(modeflag, pathname, argv) - spawn a child process
*
*Purpose:
* Spawns a child process.
* formats the parameters and calls _spawnve to do the actual work. The
* NULL environment pointer indicates that the new process will inherit
* the parents process's environment. NOTE - at least one argument must
* be present. This argument is always, by convention, the name of the
* file being spawned.
*
*Entry:
* int modeflag - mode to spawn (WAIT, NOWAIT, or OVERLAY)
* only WAIT and OVERLAY currently implemented
* char *pathname - file to spawn
* char **argv - vector of arguments
*
*Exit:
* returns exit code of child process
* if fails, returns -1
*
*Exceptions:
*
