Interesting: The problem we see/saw was that when make attempted to run 
the compiler, the command string would not get passed along, causing 
the compiler to not unreasonably complain loudly about the lack of a 
command line. We verified that make was correctly generating the 
command line, and that the error occurred somewhere in the fork that 
launched the compiler. Unfortunately, of course, we could not 
consistently reproduce the problem. (Although, typically of such 
things, it always became much, much worse whenever we were pushing for 
a release.)
