Misc questions

Hi Felix,

I'm working on CHICKEN versions of srfi-19 & srfi-29. Can I add an  
accumulating gc time counter to support the '(current-gc- 
milliseconds)' extension? I'd prefer not to have it config  
dependent . (Very low priority.)

I have srfi-1 & srfi-13 requirements but use of rationals is feature  
dependent (so at least 2 compile flows, w/ & w/o full-numeric-tower:;  
thank you BTW for the feature). Testing, and some thought,  will  
probably reveal a way to get around the use of rationals for exact  
date arithmetic.

The 'date' record is a synonym, effectively, for your date vector.  
Differing naming allows this. I will experiment w/ content copy,  
layout is the same, but for now it is a serialized set!.

The srfi-29 port is to be platform dependent (i.e. I haven't really  
worked on it). Some communication w/ Windows, Linux, etc. specialists  
in the community will be rqrd. (I can do SUS*,  MacOS X, & default.)

A release will rqr a 'format' update, for srfi-29. I guess this means  
'format-modular' also.

Best Wishes,
Kon
