There is a problem with the extend-syntax.scm that I placed on
altdorf.ai.mit.edu in archive/scheme-library/unsupported/CScheme/
yesterday. I essentially forgot to define-macro-both
"define-macro-both". The source on altdorf is fixed and I have
appended a diff to this message for those of you who don't feel like
FTPing again.
