Hello:



	I am using SCO UNIX to compile my C programs and I use DJGPP for MSDOS

porting.



	I have a problem with pclose() function. The SCO man pages explain

this:



	...



    "A stream opened by popen should be closed by pclose, which waits

for the associated process to terminate and returns the exit status of

the command. "



	...



	DJGPP pclose() function doesn't return exit status. Return 0 if pclose

is OK or return -1 if pclose doesn't terminate good.



	I change pclose() function to run like SCO UNIX. Is posible to change

this in DJGPP.



				Thanks. Juanjo Erauskin



PD: Here diff of my popen() function against DJGPP popen() function:
