dnl miscellaneous macros

dnl Prevent the configure script continuing any further if a CVS control
dnl directory is found.  The idea is to prevent files generated during
dnl configuration and build from be checked in to the CVS repository that
dnl the sources are checked into.  This should only be an issue for
dnl maintainers, not end-users.  Maintainers should configure and build in
dnl a directory that doesn't contain any CVS controlled sources and files,
dnl i.e. that doesn't contain a CVS directory.
dnl
dnl Usage: ACE_CHECK_FOR_CVS_DIR
AC_DEFUN(ACE_CHECK_FOR_CVS_DIR,
[
 if test -d CVS; then
   AC_MSG_ERROR(
     [
      This error is meant for maintainers:

      Please configure and build in a non-CVS controlled directory.
      Doing so will prevent accidentally committing automatically
      generated files into the CVS repository and help ensure that
      the generated files and build scheme are correct.
     ])

dnl Add compiler flags to the CXXFLAGS and CFLAGS variables when doing an
dnl AC_TRY_COMPILE (not ACE_TRY_COMPILE).
dnl Use this macro when adding include directories to the compiler flags,
dnl for example.
dnl Usage: ACE_TRY_COMPILE(COMPILER-FLAGS, INCLUDES, FUNCTION-BODY,

dnl Create a temporary empty file and remove it after commands are done using
dnl it.  The directory in which the temporary file will be created in must
dnl exist.  Files will be created under the source directory, not the build
dnl directory.
dnl Use this macro when you need a particular file available but want it to be
dnl empty.  This is useful to prevent conflicts with autoconf's confdefs.h
dnl header when doing an AC_TRY_COMPILE.

 dnl                   CXXFLAGS to allow the user override them.
 dnl    DCXXFLAGS - C++ debugging flags
