Re: autoconf 2.59 [was: 2.60] runs into an endless loop

Stephen> Unfortunately, Andreas's patch breaks 2.59 in the same way. [...] Stephen> Malcolm? The ultimate cause of the problem is that 2.60 fixes a bug in the internal macro m4_cdr, resulting in different return value when passed a one-member list. As Andreas found out it now returns '[]' rather than '[[]]'. The solution to the compatibility question is to make our own copy of the 2.60 m4_cdr so that we can use it with both versions of autoconf. Attached is a patch that does this. When run through 2.59 it produces a copy of configure that is identical to what is in CVS. Looking through the release notes of 2.60 I see that the definitions (but not the values) of datadir, infodir and mandir have changed. This will have to be looked into.
