This is a bug report for perl from mls@suse.de,
generated with the help of perlbug 1.39 running under perl 5.12.0.


-----------------------------------------------------------------
[Please describe your issue here]

embed.h's seed macro definition clashes with a c++ header file from
gcc45, which defines a seed() function.

/usr/include/c++/4.5/bits/random.h:

      /**
       * @brief Reseeds the %linear_congruential_engine random number generator
       *        engine sequence to the seed @p __s.
       *
       * @param __s The new seed.
       */
      void
      seed(result_type __s = default_seed);

embed.h:
#define seed()                  Perl_seed(aTHX)

This results in error messages like:
/usr/include/c++/4.5/bits/random.h:185:17: error: macro "seed" passed 1 arguments, but takes just 0
/usr/include/c++/4.5/bits/random.h:198:19: error: macro "seed" passed 1 arguments, but takes just 0

The seed macro was not public in perl-5.10, this was changed in commit
0a87c459 to fix a win32 linker error.
