    plug-ins: optionally define several float.h macros for MinGW64. · 7a7ecda4

    This plug-in failed to cross-build because these macros were not defined
    in the `float.h` of my MinGW64 environment (and they are used in some
    ilmbase headers). Just define them ourselves if they are absent. I do
    this only on MinGW environment because these should really be defined on
    Linux (and other UNIX-like, I guess?) and if they are not, we may have a
    bigger issue.
