Why is that? Can it be fixed?

I wasn't able to get that to work with my setup...

I have one Makefile that uses conditionals. It is a 1200 byte Makefile.am
which expands to a 3MB Makefile.in. I'm supporting 7 different platforms,
by copying the appropriate system dependent files into the current directory
and then using the appropriate files in the compilation.
When I build, I only want the platform dependent files built. When I build
a distribution, I want all files to be distributed.
I'm attaching my Makefile.am.
Thanks!
