           Summary: allow snn.lib to be replaced by other C runtimes
           Product: D
           Version: D1 & D2
          Platform: All
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: mrmocool gmx.de



Linking D .obj files and COFF files via UniLink has shown that we might run
into issues with different C RTLs.
And since snn.lib has to be recompiled for 64-Bit anyway, can't we remove any
non-standard dependencies in the same step:

That's pretty good. Almost all of those things are standard C.
LDIV and UDIV could easily be eliminated.
__except_list is a null asm label (it is FS:[0]).

So the main problematic ones are:
_xi_a , __acrtused_con, the __fp functions, and _Ccmp
