Compiling Mono against a system-installed Boehm GC 7.0 fails with:

GC_gcj_fast_malloc is only available in Boehm GC 6.x. Yet neither Boehm GC 6.8
nor Mono's libgc support Solaris/amd64. A backport of the relevant
configuration sections to libgc was proposed as part of
https://bugzilla.novell.com/show_bug.cgi?id=324005
but rejected at the time, and the Wiki tells users to "install the latest Boehm
GC from the Boehm web site", with the latest being 7.0 since July.
http://www.mono-project.com/Mono:Solaris
(btw it should read --with-gc=boehm instead of --with-gc=system)

The above Solaris/amd64 issue #324005 could be closed if we either update libgc
or change Mono's use of Boehm GC to not rely on dropped functions. The first
solution sounds easiest, while the latter would apply to all platforms.
