>Release:        FreeBSD 3.0-BETA i386
>Environment:
FreeBSD 3.0-BETA (ELF) built 20-Oct-98
>Description:
If the assembler "as" is invoked via "gcc -pipe xxx.s", the parameters
passed to as will end with a hyphen "-", indicating that input should
also be taken from STDIN. The assembler process will wait for input 
until EOF is read.
This may cause unexpected build failures, for example if ports come 
with assembly language files and CFLAGS=-pipe. Since GNU configure 
may contained tests for "as" features, the configure target of a port
may seem to hang indefenitely.
>How-To-Repeat:

	touch xxx.s
	cc -v -pipe xxx.s

The assembler will be called with a "-" as last parameter and will wait
for a ^D to be pressed ...

This situation is triggered by the configure script provided by the 
latest version of WINE (980927).
>Fix:
Fix the parameter processing of "gcc". As far as I can see, the assembler
does not really need "-" for the "cc -pipe" case, since STDIN is assumed,
if no file name is passed. I guess that "/usr/src/contrib/gcc/cp/lang-specs.h"
must be modified, but didn't have time to actually attempt a fix.
