    This commit adds the remainder of the outstanding PPC/Darwin port merge. · 2ff25623
    pmai authored
    Besides support for Darwin foreign loading, and updates to the ppc-vm
    and bsd-os files, this commit removes unix:unix-errno as a foreign variable
    and replaces it with a function named unix-errno, and a (setf unix-errno).
    This makes both glibc support cleaner, and enables ports like PPC/Darwin
    (and the upcoming win32 port) which have no easy way of accessing errno as
    a foreign variable able to support this functionality at all.
    
    The current implementation of this is rather make-shift, it would likely
    be much cleaner to go the SBCL way and mediate all access to errno via
    defined functions in the C runtime.
    
    As an interim feature, the frobbing of the float-trap-modes is currently
    commented out for Darwin because of ongoing breakage.
