Hi Paul,

Another minor patch. When this is in configure:

checking that `mmap' is sane... yes
checking signal received if referencing nonexistent part of mmapped file...=
 SIGBUS

The MMAP_SIGNAL macro gets defined to SIGBUS. This causes a compilation
error since signal.h needs to be included.

In file included from base.h:24,
                 from b-fro.c:24:
b-fro.c: In function =E2=80=98fro_open=E2=80=99:
../lib/config.h:1318:21: error: =E2=80=98SIGBUS=E2=80=99 undeclared (first =
