47    dnl The icc compiler has the same options as gcc, so let the rest of the
48    dnl configure script think it has gcc when setting up dnl options etc.
49    dnl This is a nasty hack which no longer seems necessary with the update

58    dnl We need to find a compiler for compiling a program to run on the local host

60    dnl There is a macro called AC_PROG_CC_FOR_BUILD in the GNU archive for
61    dnl figuring this out automatically. Unfortunately, it does not work with the
62    dnl latest versions of autoconf. So for the moment, we just default to the
63    dnl same values as the "main" compiler. People who are corss-compiling will
64    dnl just have to adjust the Makefile by hand or set these values when they
