Configure question -- how do you disable error checking in XEmacs-21.5?

I just updated my source tree to the latest XEmacs-21.5, and am trying to configure without error checking. I have tried the following without success: configure --without-error-checking configure --disable-error-checking configure --with-error-checking=none configure --with-error-checking="" Unsurprisingly, the last attempt resulted in config completing with error-checking enabled. The first three attempts resulted in the following error message: configure: Usage error: Invalid type list supplied. Valid types for the --with-error-checking option are: extents types text gc malloc byte_code glyphs display structures. A prefix of "no" (eg, "notype" for "type") turns a type off. Types not explicitly specified or negated take their defaults. The list of defaults is "extents,types,text,gc,malloc,byte_code,glyphs,display,structures". Prefixing `all' or `none' to the list sets all defaults to on and off respectively. `yes' as the sole argument is equivalent to omitting the argument. Use `configure --help' to show usage. Am I missing something? As a secondary issue, configure always exits with a status of zero even when it fails, like it does above. -- Paul Keusemann pkeusem(a)visi.com 4266 Joppa Court (952) 894-7805 Savage, MN 55378
