The only difference between -lpthread and -pthread that I could see is that the latter also sets -D_REENTRANT. However, I can't find any uses of _REENTRANT anywhere outside of a few utilities that seem to define it manually. Testing with various manually written pthread programs resulted in identical binaries, let alone identical results. Is there an actual difference between -pthread and -lpthread or is this just a historical artifact? -- Eitan Adler
