[Debian-med-packaging] Bug#790288: Please support ARM (mcontext_t/sigcontext has no member named gregs)

[Martin Michlmayr]

Package: fw4spl
Version: 0.9.2-2
Severity: wishlist
User: debian-arm at lists.debian.org
Usertags: arm64

fw4spl fails to build on at least armel, armhf and arm64 (and possibly
other architectures) with:

  error: 'mcontext_t {aka struct sigcontext}' has no member named 'gregs'

The code is:

#ifndef __MACOSX__
        ss << " from " << uc->uc_mcontext.gregs[REG_EIP];
#endif

looks like some Linux platforms have to be excluded too, or maybe
restrict this to x86 or something.  (I don't know anything about
sigcontext/gregs, so I don't know what the solution is, but please
forward this bug upstream.)
