When using -M, the gnu C preprocessor will repeat occurances of included files. This is commonly occurs in G++, where the ``#ifdef foo #define foo...'' convention is used. It's not a major hassle, it just slows down makes and causes the makefile dependency information to be much larger than necessary. -- Dirk Grunwald Univ. of Illinois grunwald@flute.cs.uiuc.edu
