Actually that's totally overboard.  I was having a bad hair day.  Sorry.

Sure I apologise for not posting first time, but it was at home, not
in the office.

This is from the reference manual for libc.a

spawn*
======

Syntax
------

     #include <process.h>
     
     int spawnl(int mode, const char *path, const char *argv0, ...);
     int spawnle(int mode, const char *path, const char *argv0, ...
	/*, const char **envp */);
     int spawnlp(int mode, const char *path, const char *argv0, ...);
     int spawnlpe(int mode, const char *path, const char *argv0, ...
	/*,const char **envp */);
     
     int spawnv(int mode, const char *path, const char **argv);
     int spawnve(int mode, const char *path, const char **argv, 
	const char **envp);
     int spawnvp(int mode, const char *path, const char **argv);
     int spawnvpe(int mode, const char *path, const char **argv, 
	const char **envp);

[cut function description]

Example
-------


     char *environ[] = {
       "PATH=c:\\dos;c:\\djgpp;c:\\usr\\local\\bin",
       "DJGPP=c:/djgpp",
       0
     };
     
     char *args[] = {
       "gcc",
       "-v",
       "hello.c",
       0
     };
     
     spawnvpe("gcc", args, environ);
