tags 794622 + patch
thanks
I’ve asked in #boost on IRC and looked through the mailing list archives
but so far, upstream doesn’t seem to have a fix.
Between 1.57 and 1.58, they added code that only handles a two-state
(32 bit/64 bit), but not the 32/64 flavour that x32 and MIPS N32 have.
I therefore experimented with a minimal patch to just address this
problem, which should not hurt i386 either because adding -march=i686
should not have been done there either as it breaks Pentium machines.
It does build. We’ll see whether it actually works.
Please find this patch applied for your convenience, and for forwar‐
ding upstream. Please do make sure this, or another patch fixing the
issue, ends up in the package, especially considering the transition.
Adam/Daniel: I’ve uploaded to unreleased.
Thanks,
