Description Jason King 2014-07-05 00:33:34 UTC 
For some time, the -mt flag on Sun's compilers expands to -D_REENTRANT -lthread.

As of Solaris 10, libthread is merely a filter library (basically a compatibility shim) as all the threading functionality now resides inside libc.  At the same time (effectively), the threading model was unified.  As such, neither flag (nor the -mt flag) is needed while _linking_.

-D_REENTRANT will still be needed while compiling and C/C++ source to get mt-enabled symbol definitions (e.g. a mt errno definition), but is not needed for D sources (as long as the mt definition is used in the .d file).

Fixed by PR #3718 but not auto-closed.
