>Description:

In NetBSD 3.0_BETA pf can't co-exist with altq, so if I'll make config with altq and pf lines, it compiles with errors like:
	/usr/src/sys/dist/pf/net/pf.c: In function `pf_send_tcp':
	/usr/src/sys/dist/pf/net/pf.c:1355: error: dereferencing pointer to incomplete type
Same with VERIFIED_EXEC, if I compile it with fingerprint hash (for ex. VERIFIED_EXEC_FP_RMD160), I'll get errors:
	kern_verifiedexec.o(.text+0x176): In function `veriexec_init_fp_ops':
	: undefined reference to `RMD160Init'
I think, config should warn about conflicts and dependences like this.

>How-To-Repeat:
	Compile kernel with VERIFIED_EXEC and any fingerprint hash, but WITHOUT pseudo-device crypto, or compile pf with altq.

 I think this is hard to do. There are far a lot more possibilities that we
 cannot predict that easily.
