[Chicken-users] Portably overwriting files

[Matt Gushee]

Hi, all--

I am working on a simple mechanism for loading and saving runtime 
configuration data for an application. When a config is saved, I want to 
replace the existing file (if any); however, it appears that for all the 
R5RS I/O procedures, the behavior is unspecified whenever you open an 
output port on an existing file. So, do I need to explicitly delete the 
existing file in order to have portable code?
