* Adjustments to GnuCOBOL package * changed build to preserve timestamps on copy, removing the need to auto-run autoconf/automake * using multiple jobs during build (not for make check as this seems to not work within MSYS2) * Updating GnuCOBOL package to 3.0 RC1 (which is considered much stable than 2.2 final) * update to 3.0 RC1 * skipcursestests.patch no longer needed - removed
