I'm not sure.  I think it's using libc regex, since ldd doesn't show any
extra libraries (apart from libm) on chicken, libchicken etc.

On closer look, the regex "^([\\-A-Za-z0-9]+):[ ]*([^ ].*)$" is obviously
invalid.  The dash after the backslashes is illegal.
To quote the manpage:
``It is illegal for two ranges to share an endpoint, e.g. `a-c-e'.''

If you want to include the - sign itself, it should be put first or last:
``To include a literal `-', make it the first or last character, or the
  second endpoint of a range.''

I'm not sure what you want to do with the backslashes.  Is it supposed to
include a literal backslash, or are you trying to escape the dash?

HTH,
Peter
