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`
- Always look into /usr/local before /usr - Added breaks to make sure the preferred value is used. 2003-10-01 02:53:23 +00:00			`test -f $i/include/readline/readline.h && READLINE_DIR=$i && break`

- There's no point in allowing using both --with-readline and --with-libedit the same time. Prefer --with-readline. - Use PHP_ADD_LIBRARY when there is no path available. 2003-02-11 03:24:30 +00:00
