SDC-32bit

[UplinkCoder via Digitalmars-d-announce]

Sorry I think i messed up with my github branches.
until i get it straightend out you can get my local working 
source verbatim from
http://www42.zippyshare.com/v/4371099/file.html
I modified the sdc to produce 32bit code if the -m32 argument is 
passed to it. 64bit is still the default.
I also modified the runner executable to use the 32bit-sdc if 
--m32 is passed to it.
Don't  recompile the runner it will only produce 32bit tests.
I modified the sdrt to get it to compile for 32bit.
Therefore everything with Execptions will fail.
