Hi Timo,
It doesn't compile for Solaris 10:
gcc concurrency.c -o concurrency -Wall
concurrency.c: In function `main': concurrency.c:40: warning: implicit declaration of function `flock' concurrency.c:40: error: `LOCK_EX' undeclared (first use in this function) concurrency.c:40: error: (Each undeclared identifier is reported only once concurrency.c:40: error: for each function it appears in.) concurrency.c:50: error: `LOCK_UN' undeclared (first use in this function) concurrency.c:92: warning: long int format, size_t arg (arg 2) Cheers.

Attached another test program. I don't expect it to print any errors with any OS, but I'd like to confirm it for non-Linux SMP kernels. (Except for OpenBSD, it doesn't work correctly in it anyway because it doesn't support mixing write()s and mmap())
