No, it should not be closed. When speaking of obsolescence I was
confusing _AM_PROG_CC_C_O and AM_PROG_CC_C_O macros.
_AM_PROG_CC_C_O is used to rewrite AC_PROG_CC:
--8<---cut here---start->8---
dnl Redefine AC_PROG_CC to automatically invoke _AM_PROG_CC_C_O.
m4_define([AC_PROG_CC],
m4_defn([AC_PROG_CC])
[_AM_PROG_CC_C_O
])
--8<---cut here---end--->8---
What needs to be done is to similarly redefine AC_PROG_CXX to use the
‘compile’ wrapper script for icl and others C++ compiler which do not
understand ‘-c -o’.
