Sounds plausible to me! I hadn't realised that the default debug mode 
for the -g option had changed. I'll stick with -gcoff as keeping the 
.exe small while retaining the debug information is useful, and the 
information provided by -gcoff has always been adequate in the past.

I'll let you know the results of the `size -A' if the .exe is still 
bloated when using -gcoff.

Thanks.
