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. >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
