Depends...

If you're also relinking all applications that use the DLLs, then
fine...  but in that case, I don't see why you bother with DLLs at
all.

What, exactly, do you intend to do with the resulting DLLs?

Yes, the top build.info is the file to make changes in for this.
However, once again, I really do not recommend this.

Cheers,
Richard

Hi Richard,

Thanks for replying.

Since I'm rebuilding and relinking from source code, do I need to be concerned
with ABI backward compatibility?

I see that build.info builds the .libs for VMS with a 32/64 suffix, the same 
naming
convention that we're using for 1.0.n, and want to keep in 1.1.n. So, maybe, our
best way forward is a small change to build.info in the IF statement for /^VC-/ 
?

Regards,
M Zarlenga
