Nice.

So we package different versions of the same library under different names. 
The library is the Boehm-Demers-Weiser garbage collector that we carry under 
the names bdwgc (7.2f), and libgc (7.4.0). The following build order seems to 
triggers the error:

	bdwgc (guile dependency)
	guile
	libgc
	make

guile links with bdwgc as a mandatory dependency. make-4.1 configure script 
finds guile and pulls -lguile-2.0 and -lgc to its link command. But libgc 
builds before make, thus overwriting bdwgc. When make attempts to link with 
libgc it fails because of missing getcontext, a problem that is fixed in bdwgc 
by a local patch.

I have verified that building guile, libgc, and make, in that order, 
reproduced this build failure.

I suggest to just remove libgc in master, event though it was added first, 
because no other package depend on it.
