Yes it fixes the stdcall testcases.

 Out of curiosity I checked to see if it affected

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=6764

which, although closed, has been on-again/off-again with DW2 on windows.
The -mno-accumulate-outgoing-args -fomit-frame-pointer combination
results in abnormal termination with (and without) your patch and the
testcase
in that PR.
