Comment (by mojca@…):
Thank you very much for the pointer.
I would actually be more inclined towards fixing `util.h` in Perl itself.
Looking at this:
* http://stackoverflow.com/questions/6526322/why-redefinition-of-
typedef-error-with-gcc-4-3-but-not-gcc-4-6
it makes me suspect that the following definitions in `util.h` are not
written properly / don't behave well with older compilers:
{{{
/* outside the core, perl.h undefs HAS_QUAD if IV isn't 64-bit
We can't swap this to HAS_QUAD, because the logic here affects the type
of
perl_drand48_t below, and that is visible outside of the core. */
#if defined(U64TYPE) && !defined(USING_MSVC6)
/* use a faster implementation when quads are available,
* but not with VC6 on Windows */
# define PERL_DRAND48_QUAD
#endif
#ifdef PERL_DRAND48_QUAD
/* U64 is only defined under PERL_CORE, but this needs to be visible
* elsewhere so the definition of PerlInterpreter is complete.
*/
typedef U64TYPE perl_drand48_t;
#else
struct PERL_DRAND48_T {
U16 seed[3];
};
typedef struct PERL_DRAND48_T perl_drand48_t;
#endif
#define PL_RANDOM_STATE_TYPE perl_drand48_t
#define Perl_drand48_init(seed) (Perl_drand48_init_r(&PL_random_state,
(seed)))
#define Perl_drand48() (Perl_drand48_r(&PL_random_state))
}}}
but I'm not yet sure how to fix that either.
Other than that I don't see any reason not to switch to `PERL_SUBVERSION`
etc. But it really makes more sense to me to fix Perl's headers.
