Hello Jeph,

Thanks for the report.

The failure of test 3 is due to a bug in Autoconf's test suite; it can
safely be ignored.

The failures of the AC_F77_WRAPPERS and AC_FC_WRAPPERS tests look like
an installation problem with either GCC or the assembler on your system,
all compilation tests fail:

Once you figure out how to fix that, those tests should pass.

No.  The native AIX shell really is so much slower than a decent shell
when handling large and complex shell scripts.  It helps _a lot_ to use
bash on AIX.  I think you can do that by configuring packages this way,
assuming bash is installed as /bin/bash:
  CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash

No, except maybe that Autoconf should find and a better shell by itself.
It's not so easy however to efficiently test for "is this shell
agonizingly slow" in a configure script.  You can install Autoconf
and use it as you like.
