I've made a complete buildworld and tried mergemaster, which worked fine. I've also checked the GNU regression tests comparing the two versions. There's little difference. The speed is varying, sometimes GNU is faster, sometimes the BSDL versions. The accuracy seems to be the same up to 18 digits after the decimal point. I've also checked the OpenBSD regression tests found only one case, which didn't work but these tests seem to be specific for BSDL bc/dc as they don't really work with the GNU version. I've made a patch, which doesn't remove GNU bc/dc yet, just detaches them from the build so that in case of a regression we can easily revert while the problem is fixed: http://kovesdan.org/patches/bcdc.diff -- Gabor Kovesdan FreeBSD Volunteer EMAIL: gabor_at_FreeBSD.org .:|:. gabor_at_kovesdan.org WEB: http://people.FreeBSD.org/~gabor .:|:. http://kovesdan.orgReceived on Tue Jun 23 2009 - 04:56:55 UTC
