-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Vincent Torri on 11/28/2009 2:22 AM: > AC_DEFUN([ECORE_CHECK_MODULE], > [ > m4_pushdef([UP], m4_toupper([[$1]]))dnl > m4_pushdef([DOWN], m4_tolower([[$1]]))dnl Lose the extra quotes. Per the NEWS, m4_toupper and m4_tolower now properly quote their expansion. So you need: m4_pushdef([UP], m4_toupper([$1]))dnl m4_pushdef([DOWN], m4_tolower([$1]))dnl and everything else should fall into place. For example, > > have_ecore_[]m4_defn([DOWN])=no with the extra quotes, this line was producing have_ecore_foo[foo]=no instead of the intended have_ecore_foo=no Sorry that this is a backwards-incompatible change, but we did document it, and it makes m4_toupper more consistent with other m4sugar text manipulation macros, in that it does not spuriously cause macro expansion of the resulting text if the case-change happens to name an existing macro. In order to write a configure.ac script that will work with both 2.64 and younger, and with 2.65, you will need a wrapper function. Here's one way to write it: m4_pushdef([AAA],[BBB])dnl m4_if(m4_toupper([aaa]),[BBB], [m4_define([my_toupper],[m4_toupper([[$1]])])], [m4_copy([m4_toupper], [my_toupper])]) m4_popdef([AAA]) and likewise for m4_tolower; then use my_toupper instead of m4_toupper. - -- Don't work too hard, make some time for fun as well!
