  5. # SYNOPSIS
  6. #
  7. # AX_PROG_CC_FOR_BUILD
  8. #
  9. # DESCRIPTION
  10. #
  11. # This macro searches for a C compiler that generates native executables,
  12. # that is a C compiler that surely is not a cross-compiler. This can be
  13. # useful if you have to generate source code at compile-time like for
  14. # example GCC does.
  15. #
  16. # The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
  17. # needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
  18. # The value of these variables can be overridden by the user by specifying
  19. # a compiler with an environment variable (like you do for standard CC).
  20. #
  21. # It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
  22. # file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
  23. # the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
  24. # substituted in the Makefile.
