++# 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.
