The major problem faced is that is near impossible to determine dependencies on #ifdef'd code. When an options value changes, or is added/removed there is no way given the current scheme to know which files should be changed. This problem is faced by *ANY* C code developed, and it's only solution is to make everything dependent on the Makefile, which in term make re-compiling everything necessary for every new config, which is a non-solution. The issue of PTY's and others is a nice discussion point, but the you are still only solving one problem with many more exist which can't be solved as easily. Natehome | help
