*Purpose:
* defines _execlpe() - execute a file with environ and search along PATH
*
*Revision History:
* 10-17-83 RN written
* ??-??-?? TC added execlpe
* 06-18-86 JMB added environment pointer which was erroneously missing
* 06-11-87 PHG removed unnecessary environment pointer (isn't this
* fun!)
* 12-11-87 JCR Added "_LOAD_DS" to declaration
* 11-20-89 GJF Fixed copyright, indents. Added const attribute to
* types of filename and arglist. #include-d PROCESS.H
* and added ellipsis to match prototype.
* 03-08-90 GJF Replaced _LOAD_DS with _CALLTYPE2, added #include
* <cruntime.h> and removed #include <register.h>
* 07-24-90 SBM Removed redundant includes, replaced <assertm.h> by
* <assert.h>
* 09-27-90 GJF New-style function declarator.
* 01-17-91 GJF ANSI naming.

*int _execlpe(filename, arglist) - execute a file with environ
*
*Purpose:
* Executes the given file with the parameters and the environment
* which is passed after the parameters. Searches along the PATH
* for the file (done by execvp).
*
*Entry:
* char *filename - file to execute
* char *arglist - argument list (environment is at the end)
* call as _execlpe(path, arg0, arg1, ..., argn, NULL, envp);
*
*Exit:
* destroys the calling process (hopefully)
* if fails, returns -1
*
*Exceptions:
