    Use simd OpenMP pragma only when available · 4115ed94
    Rodrigo Tobar authored
    The simd OpenMP pragma was introduced in OpenMP 4.0, but the code
    neither checked for the OpenMP version at configure time, nor it checks
    for it at build time. This causes compilers with older OpenMP versions
    to produce warnings when building the code, which in turn causes
    compilation errors when configuring the project by default.
    This commit adds a check on the _OPENMP macro value in all places where
    the simd OpenMP pragma is used. Alternatively one could do this check at
    configure time and disallow compilation altogether if the requirement is
    not met.
