Okay, I'll prototype with the 'open_tmpfile()' function.
I also thought about using the _POSIX_ARG_MAX and ARG_MAX symbols to determine
when the xargs approach was really needed. If the command line is within
limits, then
$(xargs cmd, list)
would expand to:
cmd list
Do you believe this is doable/portable?
Reid
FYI, a quick perusal of our systems shows:
POSIX_ARG_MAX ARG_MAX
------------- -------
Solaris 4096 1MB
HP 4096 2MB
AIX 4096 24576 Pathetic!
OSF 4096 38912 Pathetic!
NT 4096 14500 Pathetic ** 2 !
Gotta love those 2-4 byte per arg limits on AIX, OSF, and NT.

Long live incremental make!
