Does this bug affect all preprocessor directives when using -xopenmp, or
only #pragma?  I fear that it may have some big ramifications to existing
code bases if this bug plagues things like '# include' or '# define',
which occur liberally in gnulib and other open source projects.  Has Sun
been notified of their bug?  I'm wondering how best to document this
portability issue in the autoconf manual, and whether the AC_OPENMP macro
should be taught to recognize this bug.
