What exactly was the error you got without this?  I can't formulate a 
good cross-platform patch based on this report.

I can change this without breaking cross-platform compatibility.

I'll remove these for now, but I suspect something like it will have to 
go back in for VC++.  All I can say right now is, whatever VC++ needs, 
this isn't it...  I wonder what compiler uses a Windows32 directory?

The right fix is more complicated.  I'll add it to .13.

That shouldn't be necessary.  Try adding #include <stdlib.h> to the top 
of the file.  strtod is only in namespace std if you include cstdlib 
instead, and I see no good reason to use that in this case.

Remove this line from the file:

#define errno WSAGetLastError()

It shouldn't be needed.  This is in all the files where you removed the 
Windows32 #include lines.

That can be fixed with a project setting.

Speaking of the project file, are you going to send it to me?

I'm not sure what this one means.  Would you please do some research on 
this and get back to me?  I suspect it's a common problem in many 
projects (i.e. not MySQL++ specific), but I can't guess at the fix since 
I don't use BCB.
