Hi, I want to pass an additional cpp flag (-I) to the compilation process. Here is what I am doing: My configure.ac determines the additional include directory and does a `AC_SUBST([MYINCL], [$myincl])' on it. Then Makefile.am does a `AM_CPPFLAGS = -I@MYINCL@'. Is this the proper way to do it? Especially I am concerned about clobbering any previous meaning of AM_CPPFLAGS. A `AM_CPPFLAGS = -I@MYINCL@ $AM_CPPFLAGS' seams not to work. /FAU
