Recent change causes registry creation to fail

I am trying to write a scripted wine installation in a nonstandard
directory.  As part of this procedure, I set $WINEPREFIX and then run
wineprefixcreate.  This worked perfectly in 0.9.59, but in 0.9.60+ it
fails with

wineserver: chdir to config dir : Not a directory
wine: for some mysterious reason, the wine server failed to run

"regedit" fails with the same error.  Wine does run, but its registry
appears to be screwy.  For example, the DOS environment variables like
%PROGRAMFILES% and %PATH% are not set at all.

I have traced the error to a change made by Alexandre Julliard to
registry.c in mid-April [1].  Why might that change have this effect?
What should I do to avoid this problem?

Thank you,
