You see, comparing versions is a form of art.

the-macro.c

// My artistic composition is able to compare
// two versions in a single expression! YAY!
#define  FOO_AVAILABLE(major, \
                       minor, \
                       patch) \
                               \
  ( FOO_MAJOR_VERSION >major || \
  ( FOO_MAJOR_VERSION==major && \
                                \
  ( FOO_MINOR_VERSION >minor || \
  ( FOO_MINOR_VERSION==minor && \
                                \
  ( FOO_PATCH_VERSION >patch || \
  ( FOO_PATCH_VERSION==patch && \
                                \
  + - - - - - - - - - - 8)) )) ))
