Re: w3m / boehm-gc issue (really is getcontext in x86_64)

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:Dear all,
:
:I started using dragonfly not too long ago. I wanted to build w3m from
:pkgsrc on x86_64. Configure failed in a check for libgc, which is installed.
:I found out that libgc uses getcontext (and assumes it to exist) which it 
:doesn't on x86_64 dragonfly. 
:To fix boehm-gc + w3m, I just inserted a defined(__DragonFly__) into mach_deps.c 
:Would it be a good idea to port the i386 version of getcontext into x86_64? I 
:am willing to do that, then.

   Yes, it would be a good idea!  I didn't even realize that we did not
   have a getcontext() implementation for x86_64 in libc.  It looks
   fairly straight-forward if you are familiar with x86_64 argument
   passing.  If you have questions you can ask them here or on irc.
