It looks like the latest Cygwin has a problem with mkdtemp(). mkdtemp() exists in a library and is linkable, but there is no function prototype for it in the headers. The configuration system compiles a function :- /* Override any gcc2 internal prototype to avoid an error. */ | #ifdef __cplusplus | extern "C" | { | #endif | /* We use char because int might match the return type of a gcc2 | builtin and then its argument prototype would still apply. */ | char mkdtemp (); | /* The GNU C library defines this for functions which it implements | to always fail with ENOSYS. Some functions are actually named | something starting with __ and the normal name is an alias. */ | #if defined (__stub_mkdtemp) || defined (__stub___mkdtemp) | choke me | #else | char (*f) () = mkdtemp; | #endif | #ifdef __cplusplus | } | #endif | | int | main () | { | return f != mkdtemp; | ; | return 0; | } It defines 'char mkdtemp()' and links it as it is defined in a library but not in a header !
