Add a few more GCC warnings on GCC >= 2 for ".devel" builds.
From Neil T. Spring: fixes for many of those warnings:
addrtoname.c, configure.in: Linux needs netinet/ether.h for
ether_ntohost
print-*.c: change char *foo = "bar" to const char *foo = "bar"
to appease -Wwrite-strings; should affect no run-time behavior.
print-*.c: make some variables unsigned.
print-bgp.c: plen ('prefix len') is unsigned, no reason to
validate by comparing to zero.
print-cnfp.c, print-rx.c: use intoa, provided by addrtoname,
instead of inet_ntoa.
print-domain.c: unsigned int l; (l=foo()) < 0 is guaranteed to
be false, so check for (u_int)-1, which represents failure,
explicitly.
print-isakmp.c: complete initialization of attrmap objects.
print-lwres.c: "if(x); print foo;" seemed much more likely to be
intended to be "if(x) { print foo; }".
print-smb.c: complete initialization of some structures.
In addition, add some fixes for the signed vs. unsigned comparison
warnings:
extract.h: cast the result of the byte-extraction-and-combining,
as, at least for the 16-bit version, C's integral promotions
will turn "u_int16_t" into "int" if there are other "int"s
nearby.
print-*.c: make some more variables unsigned, or add casts to an
unsigned type of signed values known not to be negative, or add
casts to "int" of unsigned values known to fit in an "int", and
make other changes needed to handle the aforementioned variables
now being unsigned.
print-isakmp.c: clean up the handling of error/status indicators
in notify messages.
print-ppp.c: get rid of a check that an unsigned quantity is >=
0.
print-radius.c: clean up some of the bounds checking.
print-smb.c: extract the word count into a "u_int" to avoid the
aforementioned problems with C's integral promotions.
print-snmp.c: change a check that an unsigned variable is >= 0
to a check that it's != 0.
Also, fix some formats to use "%u" rather than "%d" for unsigned
quantities.
