Why do you do that? I've been using the _XYZ_H naming scheme for years,
and never got a problem with it. Whereas, on the other hand, identifiers
that are not prefixed with underscores give collisions more often than
you think:
  DS            /* SVR4, Solaris */
  SP            /* SVR4, Solaris */
  EAX           /* SVR4, Solaris */
  CBLOCK        /* 386BSD */
  hz            /* AIX */
  TIME_ABSOLUTE /* MacOS X */
  TIME_RELATIVE /* MacOS X */
