No, a plain ./configure does not work; that's how I've built grep always. But a './configure --disable-gcc-warnings && make' does work. $ src/grep --version | head -1 src/grep (GNU grep) 2.21.65-4f89-dirty Maybe ./configure should detect the compiler version and automatically add --disable-gcc-warnings for old versions? > (Of course you may run into problems with your old buggy > libpcre, but that's a different story....) Well, configure says this: checking for PCRE... no checking for pcre_compile... no configure: WARNING: GNU grep will be built without pcre support. So it seems I won't have problems there. :) Benno -- http://www.fastmail.com - IMAP accessible web-mail
