[nhc-bugs] Re: nhc-1.06 doesn't compile .c files

> nhc-1.06 doesn't compile .c files

I presume the .c file you want to compile is real hand-written C,
not a compiler-generated intermediate file?  If so, then yes, this
was inadvertently broken in 1.06.  A full patch is attached.

> Changing CSUFFIX from "hc" to "c" in the nhc98 driver seems to fix this.

Unfortunately, that is not a very safe fix - it will break a build
via gcc.  Better to undo that change and apply the patch below.
(After applying, a ./configure is needed.)
