 >Submitter-Id:	???
 >Originator:	Fred Koschara
 >Organization:	FKE Internet
 >Confidential:	no
 >Synopsis:	build fails on FreeBSD 4.9
 >Severity:	critical
 >Priority:	high
 >Category:	krb5-build
 >Class:	sw-bug
 >Release:	1.3.4 from krb5-1.3.4.tar downloaded 6/24/2004
 >Environment:	P4/866 384MB RAM
		FreeBSD 4.9-RELEASE (build and target)
		gcc 2.95.4
 >Description:

configure issues several warnings, including
	Could not find Tcl which is needed fro some tests
	krb_db.h: present but cannot be compiled
	krb_db.h: check for missing prerequisites headers?
	krb_db.h: proceeding with the preprocessor's result

make issues warnings for nearly all successfully compiled files:
	/usr/include/stdlib.h:111: warning: ANSI C does not support 'long long'
	/usr/include/stdlib.h:117: warning: ANSI C does not support 'long long'
other make warnings include:
	error.c:71: warning: no previous prototype for 'ss_error'
	dk_decrypt.c:163: warning: pointer targets in assignment differ in signedness
	(other, similar warnings in dk_encrypt.c, derive.c, ...)
	stringtokey.c:79: warning: cast discards qualifiers from pointer target type
	(many warnings in aes.c)
	yarrow.c:448: warning: negative integer implicitly converted to unsigned type
	(...)

The build eventually dies:
	In file included from /usr/include/sys/param.h:98,
			 from ftp_var.h:111,
			 from ./cmdtab.c:39:
	/usr/include/sys/signal.h:230: redefinition of 'my_sig_t'
	ftp_var.h:62: 'my_sig_t' previously declared here
	./cmdtab.c:35: warning: 'sccsid' defined but not used
	*** Error code 1

	Stop in /software/Kerberos/krb5-1.3.4/src/appl/gssftp/ftp.
	<...>

 >How-To-Repeat:

I have captured the configure and make output using this shell script:
	./configure -- prefix=/usr --enable-shared > config.stdout 2>&1
	make > make.log 2>&1

Please advise if you would like to have me send either of these files 
and/or the config.log file, or any other information needed to resolve this 
problem.

 >Fix:

I suspect configure made an erroneous assumption about the build 
environment:  This looks rather like the kinds of warnings and errors that 
I see when trying to build winDoze programs with the wrong 
compiler.  However, I don't know enough about the gcc build process, etc. 
to identify the underlying invalid assumption and correct it.

The "war on terror" is a sham:  There is no real protection against 
suicidal maniacs spurred on by creative madmen.  In the end, the only 
outcomes will be the destruction of the American economy due to pouring a 
bankrupting stream of wealth into a bottomless pit, and the final 
destruction of personal liberty in the name of "security."  (When was the 
last time you were asked for "Your papers, please?" - er, that is, "License 
and registration?")

The rumors are untrue:  I am *not* running for President in 2004...
