Done. Uploaded Firebird-3.0.7.33374-0.tar.bz2 and removed the other 
versions.

I was looking into building 3.0.7 when trying to build Firebird for 
Windows Arm64. I'm really wondering, why we build Firebird on Windows 
with a heavily patched configure, which doesn't support cross building 
at all. Any reason not to use VS / msbuild solutions? Has anyone tried that?

We use msbuild for quite a few external dependencies, like Python.
