[xsd-users] Too many anonymous types

[Brian Young ARA/CFD]

I verified the build runs on my schema using at most 70MB RAM, and using
lower cpu consumption than before. In addition, it produced over 2500
cpp/h files in well under 2 minutes.

Note, I have not yet inspected or used the generated --file-per-type
code, but your fix is verified.

I think I've identified and fixed the cause of this high memory usage.
At least my schema that used to cause XSD to run out of 2GB of RAM in
the --file-per-type mode now compiles fine using only 2% of that memory.

Would it be possible for you to test this fix on your schema and let me
know if there is an improvement? I've built a pre-release binary which
you can get here:
