[nhc-bugs] a problem with "clean"?

Hello, Just a minor gripe. I wanted to increase the default heap size, so just to be on the safe side I cleaned up the subdirectories created by "install", then did "gmake clean", run "config" with the new parameter and tried to build again:

time gmake all gmake: *** No rule to make target `src/compiler98/*.hc', needed by `targets/ix86-OpenBSD/compiler-gcc'. Stop.

I had to import the entire tar file again. Could it be that "clean" was a bit too eager? Or not eager enough? Regards, -- Feliks
