>Release:        Oct 30, 1998
>Environment:
System: NetBSD fb.sa.enteract.com 1.3H NetBSD 1.3H (FB) #135: Fri Oct 30 11:40:15 CST 1998
fredb@fb.sa.enteract.com:/usr/src/sys/arch/mac68k/compile/FB mac68k


>Description:
	libpcap built against Friday's sup is not usable. Example:

#pppd call enteract
/usr/libexec/ld.so: Undefined symbol "_pcap_lval" in pppd:/usr/lib/libpcap.so.0.0

moreover, pppd fails to link staticly:

#LDSTATIC=-static make
cc  -static -o pppd auth.o cbcp.o ccp.o chap.o chap_ms.o demand.o fsm.o ipcp.o ipxcp.o lcp.o magic.o main.o options.o sy
s-bsd.o upap.o -lpcap -lcrypt -lutil
gencode.o: Undefined symbol `_pcap_parse' referenced from text segment
grammar.o: Undefined symbol `_yylex' referenced from text segment
grammar.o: Undefined symbol `_yylex' referenced from text segment
scanner.o: Undefined symbol `_pcap_lval' referenced from text segment
scanner.o: Undefined symbol `_pcap_lval' referenced from text segment
scanner.o: Undefined symbol `_pcap_lval' referenced from text segment
scanner.o: Undefined symbol `_pcap_lval' referenced from text segment
*** Error code 1

Stop.
>How-To-Repeat:
	Build the world against October 30's sup. Try to run pppd.
>Fix:
	The following seems to work.

	eeprom might need similar magic; it appears to have the only other Makefile 
	in the tree that sets YFLAGS in this way...
