Well, the script in question is from the gawk-3.1.0.tar.gz released by 
Arnold Robbins, and the test program is also commented as being 
authored by him.

However, there *is* a workaround.  The configure.in already has 
specific bypasses of this test for VMS and BeOS, and it was fairly 
trivial to add "MS-DOS" as another bypass case, which is the "right 
thing" for DJGPP (void argument to getpgrp).

I will do that.  I also found another error in the M4 test he wrote for 
the strtod function, which I will also send to him.

BTW, even though the gawk-3.1.0 package has a pre-built "makefile" and 
other files for "pc" use, including DJGPP, I am trying to see how few 
"special purpose" DJGPP exceptions need to be used to build the package 
starting with configure and the all the latest DJGPP ports.

It's a "configure" learning exercise for me, but I'll pass on anything 
else I find to Arnold as I find them.

Thanks for the advice.
