-# SYNOPSIS
-#
-# AX_PROG_CC_FOR_BUILD
-#
-# DESCRIPTION
-#
-# This macro searches for a C compiler that generates native executables,
-# that is a C compiler that surely is not a cross-compiler. This can be
-# useful if you have to generate source code at compile-time like for
-# example GCC does.
-#
-# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
-# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
-# The value of these variables can be overridden by the user by specifying
-# a compiler with an environment variable (like you do for standard CC).
-#
-# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
-# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
-# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
-# substituted in the Makefile.
