Hi! I have built a windows-make version of the release-canditate versions 3.99.91 and 3.99.92, using Visual Studio and MinGW. The result, I.e. make fails if I'm using parallel builds and the feature 'output-synchronization' with an error like 'could not create tmpfile'.
After spending some time for debugging, I have detected the "problem": - A temporary file is used to buffer the outputs (of course) - this file is created with calling 'tmpfile()'. As written in http://msdn.microsoft.com/en-us/library/x8x7sakw%28v=vs.90%29.aspx, tmpfile() does create a temporary file in the root directory; But in many cases - e.g. inhibited by NTFS-security or if UAC is active - a creation of files in the root-directory is forbidden. IMHO, I think, this type of temporary files should be created like other needed temporary (batch-) files in the TMP/TEMP-folder (using the associated environment variable). Best regards from Salzburg, Markus
