One more thing: Solaris open(...) has a Solaris-specific flag O_NOLINKS that can cause open to fail with errno==EMLINK. This is a valid extension to POSIX, so if O_NOLINKS is also given the wrapper shouldn't convert EMLINK to ELOOP. This shouldn't add to the number of syscalls either, but I thought I'd mention it since one can trigger that issue with "dd oflag=nofollow,nolinks ofile=foo" on Solaris. Come to think of it, it might be more conservative to convert EMLINK to ELOOP only if both (1) O_NOFOLLOW is given and (2) no flags are given other than those standardized by POSIX.
