(I have not had time to try Ubuntu and fedora, but I expect to see the identical behaviour). No regressions noted. This is with 'make check; make selfcheck; make install' along with a git build. This does not help with platforms I don't have available, of course (particularly mips/arm), but it is something. ;-) I have some minor comments on the patches, but I will have to wait until tomorrow now (I have to get some sleep). However, there was one thing I wanted to mention tonight. These patches change the interface of cgcc in a non-backward compatible way. In particular, the -target=<spec> parameter, which can and pretty much _had_ to be specified multiple times (well OK twice in practice), to specify _both_ the 'OS' and 'arch' specs. Before these patches, the <spec>s available to the -target parameter was: sunos linux gnu/kfreebsd openbsd freebsd netbsd darwin gnu unix cygwin i386 sparc sparc64 x86_64 ppc ppc64 s390x arm aarch64 host_os_specs host_arch_specs After these patches, the <spec>s available are now only: i386 sparc sparc64 x86_64 ppc ppc64 ppc64+be ppc64+le s390x arm arm+hf aarch64 Note that the tokens 'host_os_specs' and 'host_arch_specs' were useful (even though they _could have_ been replaced on the command-line by "$(uname -s)" and "$(uname -m)" respectively). This is a bad loss of functionality. I have to go now. ATB, Ramsay Jones
