The default compiler paths (usually /usr/include and /usr/lib) should not be added, because non-default paths should always take precedent. Some recent compilers are even eliminating these paths automatically. The simplest case is an outdated system library in /usr where you want to compile against your own version in ~/myroot. You can achieve the latter by supplying appropiate CPPFLAGS/LDFLAGS. The autoconf system should not try to overrule that. In my particular case, I was building a set of binaries for glibc 2.1 on a glibc 2.3 based system. When adding -L/usr/lib, gcc would try to build a binary using (1) the glibc 2.1 dynamic linker/C library and (2) a library compiled against glibc 2.3. That confuses the hell out of ld, because (2) expects newer symbols which simply don't exist yet in (1). - Sascha
