Spot on Milan - that is what I've been saying!

It's Pierre who is saying that it is important which compiler version of
fbclient.dll is used with php_interbase.dll and he is saying that the version
of fbclient.dll used with php_interbase.dll has to be built with VC9 unless we
are talking to Apache when it needs to be VC6.

We are probably going back to Interbase client days when WHICH client was used
was more critical, and my normal practice is probably well out of date now,
but until I get a "Yes - using different versions of the client in parallel on
the same machine is perfectly stable" then I'll stick with ensuring that I
have just one copy - which is the correct build the target server? And then I
only have one copy to update if I update the server?
