Linux secundus 2.0.30 #8 Mon Oct 6 15:14:50 CDT 1997 i586 unknown
gcc version
The docs for mod_include sez: "cmd -- The server will execute the given string using /bin/sh.
The include variables are available to the command. "

But if arguments are given it fails with a 'cannot stat program' in the cgi log;
without args, it works o.k. (At least this is true in a suexec environment.)

The workaround is to package what would be arguments into a script without args
and call the arg-less script through the SSI.
Working:  http://www.themarquis.com/index.shtml

Failing:  http://www.themarquis.com/showbug.shtml

These are identical except that the working one execs a script that contains
what the failing one calls directly via 'exec cmd=...'.
suexec.c does not parse the cmd at all.  It passes the whole command string
to lstat.  Instead, pass everything up to the first whitespace character to lstat, not the
whole string
