System: NetBSD splode.eterna.com.au 1.1B NetBSD 1.1B (_splode_) #294: Sat Mar 30 02:04:22 EST 1996 mrg@splode.eterna.com.au:/orb/q/build/src/sys/arch/sparc/compile/_splode_ sparc


>Description:

	cc is passing a -K flag to as(1) when called with -fPIC.  this
	causes as(1) to whine about it.

>How-To-Repeat:

	i found this while attempting to compile perl with a dynamic
	library libperl:

splode t/mrg/perl5.002> cc -v -c -O -DPIC -fPIC regcomp.c
gcc version 2.7.2

End of search list.
 /usr/libexec/cc1 /var/tmp/cc003884.i -quiet -dumpbase regcomp.c -O -version -fPIC -o /var/tmp/cc003884.s
GNU C version 2.7.2 (sparc) compiled by GNU C version 2.7.2.
 as -k -K -o regcomp.o /var/tmp/cc003884.s
*unknown*: Assembler messages:
*unknown*:0: Warning: as: I don't understand 'K' flag.

	this doesn't occur with -fpic.


>Fix:

	as our as doesn't appear to have the -K flag at all, the
	following patch to gcc/arch/netbsd.h should do the right
	thing.
