Subject: Allow --enable-debugging to have a third value.
X-Git-Tag: mit-scheme-pucked-10.1.2~16^2~117
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=72fbb947027dd4c399eeea7f98d659f39f9b1e2d;p=mit-scheme.git

Allow --enable-debugging to have a third value.

Anything other than "yes" or "no" will be interpreted as setting the C compiler
to generate debugging symbols, but not turn on all of the debugging helpers in
the microcode.
