So, I have set up an environment with VC tools, and have been able to
reproduce the failure. The problems were less trivial than I though
first:
1) - The file tree list was not correctly generated, build script
generating vcproj file missing tree dependencies when listing items in
Filter. For example, for a path like src/backend/access, it missed to
list "src", "backend" and "access", listing only the files in such
paths.
2) I noticed that VC builds do not like *at all* file paths with
forward slashes, perhaps it could be possible to use a Condition like
hasForwardSlashes but it seems safer to simply enforce the file paths
to use backslashes in the vcproj files. That's inconsistent with the
vcxproj files, but it works and Mkvcbuild.pm works as before.
3) I found why chkpass was needed as a dependency with libpgport and
libpgcommon, actually crypt.c needs to be listed as a unique file, so
it needs a fake entry in vcproj and vcxproj files.
All those things are corrected in the patch attached, tested with both
MS and VC. The build is still failing because of cac76582 that
introduced the transforms, but at least it will partially cure
currawong and put it at the same level as the other machines.
