[m-dev.] diff: Fix for boehm_gc using glibc 2.1

[Peter Ross]

Hi,


===================================================================


Estimated hours taken: 0.5

Fix a bug with glibc 2.1 on linux machines.

boehm_gc/os_dep.c:
    Make sure the correct sigcontext.h gets included depending on
    which version of glibc we are using.
