Two questions: warning: macro `AM_CPPFLAGS' not found in library and how to assign values?

[Joost Kraaijeveld]

Hi,

I am getting this warning (and if I configure an error, "AM_CPPFLAGS:
command not found") for the piece of configure.ac below. What is the
correct way to achieve what I want: an incremental build up of
AM_CPPFLAGS?

And a second question: should all these assignments work 

1. PLATFORM_CPPFLAGS = -DLINUX_DLL   // spaces
2. PLATFORM_CPPFLAGS=-DLINUX_DLL     // no spaces 
3. PLATFORM_CPPFLAGS = "-DLINUX_DLL" // spaces and ""
4. PLATFORM_CPPFLAGS="-DLINUX_DLL"   // no spaces and ""

and if not which one should work? I can only make the "no spaces and """
work but I see (1) in almost all documentation?

TIA
