Newsflash: The Build-Machine for S12 has been updated from build 66 to build 79 and the complete set of SFE packages is currently rebuilt. SFEgcc is now at 4.8.5 (with LINK_LIBGCC_SPEC)
Update 20150810: the rebuild works, one highlight will be boost 0.58 and anoter highly desired package will hopefully work (wou'll have to guess which one can be based in the supporting libs snet to svn during the past few days)
