Yes, it should be, but it is not. Perhaps this is a bug in SGI's ksh,
but it only shows up in configuring wml.

This gives exactly the same failure as executing "./configure" or "sh
configure". As I said, the workaround is to use bsh.

Sure, it's on it's way...

I don't think this is an SGI problem, but as I said, I'm not that much
of a C programmer. The default option for cc is "-ansi". When
compiling with the default, or with "-xansi" (ansi with extensions),
the compilation fails. The way to get it to succeed is to use "-cckr"
which accepts K&R C, non-ansi. To me, this suggests that the code is not
ansi compliant. Here are the errors reported...
