BTW, Mac OS - Mountain Lion, with XCode 4.4

Attach the main.log file. However, we probably cannot help you with pre-release versions of OS X or Xcode, and it may contravene your non-disclosure agreements to discuss them here.

Fix : add this line

#define POSIX_C_SOURCE

at the beginning of the ${worksrcpath}/contrib/ossd-uuid/ossd-uuid.c file.

Now mountain lion is out and problem is there. I see "conflicting types" issue with apple's default clang compiler. If I add mentioned line then which commands and from which location should I run to continue compilation or start a new compilation with modified source?

Dup of #35153.
