Debugging hints

This is rather out of date now

Edit the Makefile and make sure the C compiler flags
```
-O2 -g
```
are present.
Check your C compiler is 2.7.2 using 'gcc -v'
make clean
make

Run the resulting binary under gdb:

gdb pnpdump
...
(gdb) run <pnpdump command line parameters>
...
program runs and crashes
...
(gdb) bt
...
(gdb) q

Fix the bugs found !
Send me the patch made using
```
diff -u oldfile newfile
```
along with the other information.
