With this Denemo starts up looking very good - no error messages from
any of the scheme executed on startup. However the symbol make-regexp is
undefined. Denemo executes 

(use-modules (srfi srfi-1)) ; List library
(use-modules (srfi srfi-8)) ; Returning and Accepting Multiple Values
(use-modules (srfi srfi-13)) ; String library
(use-modules (ice-9 regex)) ; regular expressions
(use-modules (ice-9 optargs)) ; optional (define* ) arguments
(use-modules (ice-9 q)) ; queue module

at startup.
I have displayed (defined? 'make-regexp) and it is #f from before the
first of those module loads and remains #f throughout.
I am not sure if it is defined or merely re-defined by (ice-9 regex).

Could this be a side effect of those initialization calls made in the C
code? Or is this a separate problem? ... I realize that I don't know for
sure that srfi-1 has successfully loaded - is there a simple test for

Thanks for your patience,
