-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Ralf Wildenhues on 3/23/2008 5:44 PM: | Hello Eric, | | I think an inadvertent backward incompatibility has been introduced. It was intentional - POSIX requires m4wrap to have FIFO behavior: http://git.sv.gnu.org/gitweb/?p=m4.git;a=commitdiff;h=ca0ae27 | I'm pretty sure this problem is rather recent. Rather, Autoconf 2.59 was relying on an M4 bug, which has since been patched in autoconf: http://git.sv.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=814d1a1 However, the m4 patch mentioned above also mentions a way to restore the older m4 behavior, in examples/wraplifo.m4. Modulo quoting differences, this could be used to guarantee correct autoconf 2.59 behavior on those projects that are not yet ready to upgrade. - -- Don't work too hard, make some time for fun as well!
