It seems many people have been compiling against 6.8, manually setting
CFLAGS &c, apparently without bad results.

It also says this:

    Guile's ./configure script uses pkg-config to discover the correct
    compile and link options for libgc.  If you don't have pkg-config
    installed, or you have a version of libgc that doesn't provide a
    .pc file, you can work around this by setting some environment
    variables before running ./configure:

    - PKG_CONFIG=true

    - BDW_GC_CFLAGS=<compile flags for picking up libgc headers>

    - BDW_GC_LIBS=<linker flags for picking up the libgc library>

Ludovic, is there a reason to *require* 7.x, given that 6.8 seems to
work fine for people?
