I would use here the platform API "GetTempPath". This seems to be the best solution here. In general TEMP and/or TMP are defined in environment, but they need to be there defined. So This functions should do the proper thing for win32 targets (beside cygwin, as here /tmp/ is of course valid). Kai -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43844
