Which is what CLANG38 does - so why do we need a completely new toolchain profile?

Can we note already build under all of these operating systems with the GNU binutils linker? When developing under Linux, I will use the toolchain provided by my distribution. / Leif -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
