Honestly I find such enforced C/C++ difference very unfortunate... e.g. if (Opts.CPlusPlus) Builder.defineMacro("_GNU_SOURCE"); Solaris seems the only exception that defines these Large File Support extension macros on the compiler driver side. Isn't it possible to do it in a common system header file? That rationale will be better than this paragraph in the description: > make check-all currently fails on x86_64-pc-solaris2.11 when building with > GCC 9: With the current description, a casual reader (like I) would just think this patch is probably not doing things at the correct layer.
