Fixed two problems: - CGI_BINARY was defined always thus this extension could be compiled with even when not building CGI binary. - HAVE_READLINE => HAVE_LIBREADLINE (typo) 2001-08-22 10:25:24 +00:00

Always prefer user specified paths over the default /usr /usr/local. This may fix compilation problems with on systems with multiple copies of the same library. 2003-09-30 22:36:43 +00:00			`for i in $PHP_READLINE /usr/local /usr; do`
