Summary: plpfuse fails to build on Linux x86_64

Initial Comment:
When building plptools on a 64-bit Linux system, configure fails to find libfuse:

checking fuse.h usability... no
checking fuse.h presence... no
checking for fuse.h... no
checking for fuse_new in -lfuse... yes
checking for supported FUSE API version... no

The configure log shines a little more light on this:

configure:19897: checking fuse.h usability
configure:19897: gcc -c -g -O2 -Wall -W -Wmissing-prototypes -Wstrict-prototypes -pedantic  conftest.c >&5
In file included from /usr/include/fuse/fuse.h:26,
                 from /usr/include/fuse.h:9,
                 from conftest.c:135:
/usr/include/fuse/fuse_common.h:32: error: #error Please add -D_FILE_OFFSET_BITS=64 to your compile flags!
configure:19897: $? = 1


If you attempt to build plpfuse regardless, the same error occurs:

make: Entering directory `/home/philpem/psion/plptools/plptools-1.0.10/plpfuse'
g++ -DHAVE_CONFIG_H -I. -I.. -I../lib    -g -O2 -MT main.o -MD -MP -MF .deps/main.Tpo -c -o main.o main.cc

                 from rfsv_api.h:30,
                 from main.cc:46:
/usr/include/fuse/fuse_common.h:32: error: #error Please add -D_FILE_OFFSET_BITS=64 to your compile flags!


-- Workaround --
The configure script isn't using the right CFLAGS on x86_64. This patch works around the bug, though it may not be the right way to do it:

--- configure.ac	2010-06-24 11:14:07.000000000 +0100
+++ ../plptools-1.0.10-mod/configure.ac	2010-10-04 23:37:04.000000000 +0100
