I have prepared a new test version of Autoconf, Autoconf 2.57, which should fix the AIX bug. Can you please give it a try on an AIX host?
Also, Kevin Ryde, could you please also try Autoconf 2.57 on a recent HP cc +O3? If it works on AIX, I'll make it an official version; if not, we'll need to prepare an Autoconf 2.58. ftp://alpha.gnu.org/gnu/autoconf/autoconf-2.57.tar.gz (1.1 MB) ftp://alpha.gnu.org/gnu/autoconf/autoconf-2.57.tar.bz2 (811 kB) Here are the MD5 and SHA1 signatures: 407ea53787ce13f5ca427e9a51e05bc2 autoconf-2.57.tar.bz2 7c0b1e10d57facb8b58f95cef0dee0f1 autoconf-2.57.tar.gz 2faead0127edb15fff9ad8b7a84837e32fa25921 autoconf-2.57.tar.bz2 957cb551fed9b7ed5b34f1207512dfb676731754 autoconf-2.57.tar.gz
