[ruby-core:44962] [ruby-trunk - Bug #6407] Most Test Failure for BigDecimal on 64bit Windows, any GCC parameter needed?

Issue #6407 has been updated by phasis68 (Heesob Park).


Due to the Revision r33978, this issue is not occurred with the trunk version.
I think r33978 should be backported to 1.9.3.

Target version: 1.9.3
ruby -v: ruby 1.9.3p194 (2012-04-20) [x64-mingw32]


Compiled with MinGW64, GCC (4.6.3) or (GCC 4.7.0), configure as ./configure --build=x86_64-w64-mingw32 CFLAGS="-O2 -finline-functions -I/usr/local/include" LDFLAGS="-L/usr/local/lib" ,after compiled, zero error on make test. but when make test-all, a lot of issue reported on BigDeciaml, I tried to add -mieee-fp,but issue is still,any extra parameter i need for gcc?
