           Summary: Solaris no longer needs -mt during linking
           Product: D
           Version: D2
          Hardware: x86
                OS: Solaris

          Priority: P1
         Component: DMD

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).
