2.59: AC_FUNC_SETVBUF_REVERSED broken on Intel C++ 8.0.055

[Matthias Andree]

Hi,

AC_FUNC_SETVBUF_REVERSED does not work properly with Intel C++ 8.0.055
"icc" and always returns "yes" on my SuSE Linux 8.2/glibc 2.3.2 system.

Minimal configure.ac:

AC_INIT
AC_FUNC_SETVBUF_REVERSED

Command line:

env - INTEL_LICENSE_FILE=$INTEL_LICENSE_FILE \
PATH=/usr/bin:/bin:/opt/intel_cc_80/bin ./configure CC=icc

Resulting config.log:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure CC=icc
