Upstream changes:
version 0.011; 2010-08-21
* bugfix: add a typemap entry for "const char *", to make XS version
of scalar_class() work correctly on Perl 5.6, having been broken by
the const fix in version 0.010
* in XS code, on Perls where it exists (prior to 5.9.5), treat SVt_PVBM
as a scalar referent type
version 0.010; 2010-08-20
* in XS, use PERL_NO_GET_CONTEXT for efficiency
* use full stricture in test suite
* also test POD coverage of pure Perl implementation
* in test suite, make all numeric comparisons against $] stringify it
first, to avoid architecture-dependent problems with floating point
rounding giving it an unexpected numeric value
* make XS code const clean for gcc -Wwrite-strings
* in Build.PL, explicitly set needs_compiler to avoid bogus
auto-dependency on ExtUtils::CBuilder
* in Build.PL, explicitly declare configure-time requirements
* add MYMETA.yml to .cvsignore
