Re: Hard time figuring out what order-only prerequisites really do.

First, it would be great if you could make your attachments as easy as possible (eg send text files only).  It would be even better if you could create minimal makefiles (eg use "echo" rather than calling "gcc", eliminate unnecessary stuff like macros, 
...) that demonstrate the problem and just paste them directly into the makefile.  Many times, while trying to create this minimal example, you yourself can find and fix the problem.  IOW, make it as easy as possible for others to help you.

It would also help if you could copy and paste command lines and output so we 
can see what's going on.  Again, only post things you think contains 
information that will help find the problem.

Anyway, what version of GNU make are you using?  Do you have all the necessary 
patches installed?  Check on Savannah (http://savannah.gnu.org/).
