Created attachment 26653
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26653
proposed patch
sorry for pr51500 attachment 26584, it was very bad idea.
thiscall trampoline uses call insn so it needed to create related stub
function.
i was releutant to create stub function in win32.S and it resulted in disaster.
in this patch these problem is considered.
and thiscall trampoline subs esp and then call fun, this is bad idea. it works
only when #of argument is 1.(passed only this)
already i encountered the problem that are described above.
`/tmp/gcc/i686-pc-mingw32/libjava/.libs/libgcj-13.dll' has changed; re-reading
symbols.

in this case string parameter is wrong.
