The problem with current trunk and windows (i.e. guile-1.6) is that Geert 
Janssens committed r18541 claiming that the replacement SCM_STRING_CHARS -> 
scm_to_locale_string is necessary to fix bug#582325, "Crash when setting Fancy 
Date format" (with lenghtly explanations there). Geert then informed us he 
will be out of town until at least January 10th, which explained why he hasn't 
replied to any of the questions here.

The first compile problem with r18541 is one of many guile-1.6 functions which 
Geert replaced with their non-deprecated guile-1.8 counterparts, such as 
SCM_NFALSEP -> scm_is_true. But even if we reverted all of that "cosmetics", 
the main part of fixing bug#582325 is still a problem because guile-1.6 
doesn't have scm_to_locale_string. Or, in other words, bug#582325 doesn't 
occur in guile-1.6 but only in the recent guile-1.8 but there it can be fixed 
only by using a new guile function which is not yet available in the old guile 
version.

Maybe we should provide a #define workaround for scm_to_locale_string if 
guile-1.6 is detected, and (unfortunately) revert the rest of the renamings?
