Hi Angelo, well, after a somewhat bumpy start on the Cygwin list, I did get the information I needed. It turned out that the directories and files I had created under Windows had the permission 000 according to Cygwin, but I could still read the files and enter the directories, because the Windows permissions allowed it.
However, if the build process _copied_ a file to the work directory, it inherited the 000 permission and this time it was properly translated to the equivalent Windows permissions. (At least, that is my interpretation of what was going on) I repaired the parent directory's permissions and now the build is continuing.
