And even after fixing that, the test still failed for me, because I got this output: ./compile.at:186: ./configure $configure_options stdout: configure: loading site script /usr/local/share/config.site # 1 "conftest.c" # 1 "<built-in>" #define __STDC__ 1 ... ./compile.at:191: sed '1,/# 1 "conftest\.c"/d' stdout --- - 2010-07-21 16:03:38.344750000 -0600 +++ /home/eblake/autoconf/tests/testsuite.dir/at-groups/253/stdout 2010-07- 21 16:03:38.282250000 -0600 @@ -1,3 +1,134 @@ +# 1 "<built-in>" Whoops - the fact that I have a config.site installed made for a false failure (there are two "conftest.c" lines, and the insertion of an extra line made the sed script stop at the first instead of the intended second).
