Here's a short status report for trunk on x86_64-w64-mingw32 host. I know this is only a secondary platform, but there are some serius issues.
Especially the ada part is in a bad shape compared to 7.3.0, see https://gcc.gnu.org/ml/gcc-testresults/2018-02/msg00439.html and https://gcc.gnu.org/ml/gcc-testresults/2018-02/msg00308.html At least 20 of the acats tests catch all memory until the host memory is exhausted. Same holds for the two libstdc++ tests 23_containers/unordered_set/requirements/exception/basic.cc and 23_containers/unordered_set/requirements/exception/propagation_consistent.cc For gcc 8.0.0 I had to disable lto due to the recent changes. A second headsup, bintuils 2.30 breaks bootstraping for x86_64-w64-mingw32. I get ICEs for the stage 2 compiler when configuring libgcc in stage 2, see https://gcc.gnu.org/ml/gcc/2018-02/msg00034.html Rainer
