    ENH: Improve robustness of compiler INFO strings · b8fc8b32
    Brad King authored
    Compiler INFO strings built at preprocessing time encode information
    that must appear as a string literal in the resulting binary.  We must
    make sure the strings appear in the final binary no matter what compiler
    and flags are used.  The previous implementation worked in most places
    but failed with the GNU linker's --gc-sections option which managed to
    discard the string.  Instead we make the program return value depend on
    an element of the string indexed by a runtime program parameter, which
    absolutely requires the string to be present.
