Fix a bug whereby 'mformat' could end up passing uninitialized bytes to write(2). This could be reproduced with: mformat -C -f 1440 -L 16 -N 77777777 -i /tmp/x :: where the output of /tmp/x would be non-deterministic.

2020-07-24gnu: gcc: Fix libstdc++ misconfiguration....Fixes <https://bugs.gnu.org/42392>. Reported by Maxim Cournoyer and Erik Garrison. Until now, the generated <bits/c++config.h> would be incorrect (many _GLIBCXX_HAVE macros would be undefined), which in turn would lead to build failures for most C++ programs. * gnu/packages/gcc.scm (gcc-6)[inputs]: Add LIBSTDC++-HEADERS. (libstdc++, libstdc++-headers): New variables. * gnu/packages/gcc.scm (gfortran): Change first argument to 'custom-gcc' to remove dependency on LIBSTDC++-HEADERS. Ludovic Courtès

2020-06-30gnu: gfortran: Remove unusable versions....The gfortran packages cannot be used without being wrapped with gfortran-toolchain. However, as the comment in (gnu packages commencement) explains, there cannot be more than one gfortran-toolchain package because of ABI issues. Thus, versions of gfortran other than the main one are useless. * gnu/packages/gcc.scm (gfortran-4.8, gfortran-4.9, gfortran-5, gfortran-6, gfortran-7, gfortran-8, gfortran-9): Remove variables. (gfortran): Define the gfortran package based on the gcc variable. Jakub Kądziołka
