From: Chris Hanson Date: Wed, 10 Jan 2007 08:00:38 +0000 (+0000) Subject: Restructure handling of optional libraries; new code is simpler and X-Git-Tag: 20090517-FFI~802 X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=73f2372ccd8f42260ee705f6dcadcc87ec86a2ef;p=mit-scheme.git Restructure handling of optional libraries; new code is simpler and hopefully more effective. In particular, problems identified by Aaron Hsu should now be addressed. Additionally, many changes were made to conform to the autoconf shell programming guidelines. A user-visible change is that --with-FOO may now specify a path, so that --with-FOO=BAR adds "-IBAR/include" to CFLAGS and "-LBAR/lib" to LDFLAGS. --- diff --git a/v7/src/microcode/configure.ac b/v7/src/microcode/configure.ac index 08875d51f..28dea600a 100644 --- a/v7/src/microcode/configure.ac +++ b/v7/src/microcode/configure.ac @@ -1,7 +1,7 @@ dnl Process this file with autoconf to produce a configure script.
