/usr/include/fenv.h in NetBSD 7.0_RC1 has:
---
#if !defined(__aarch64__) && !defined(__arm__) && !defined(__i386__) \
    && !defined(__hppa__) \
    && !defined(__sparc__) && !defined(__x86_64__)
#error  "fenv.h is currently not supported for this architecture"
#endif
---
so I guess alpha, mips, powerpc, sh3 and vax also fail to build perl,
i.e. pkgsrc is almost unusable.


>How-To-Repeat:
cd /usr/pkgsrc/lang/perl && make package

>Fix:
No idea, but "to implement <fenv.h> for all NetBSD MACHINE_ARCH" is
too late because 7.0_RC1 is already out.
