Applied:

/cvsroot/CMake/CMake/Source/cmDependsC.cxx,v  <--  cmDependsC.cxx
new revision: 1.27; previous revision: 1.26
/cvsroot/CMake/CMake/Source/cmDependsC.h,v  <--  cmDependsC.h
new revision: 1.19; previous revision: 1.18

In order to compile on GCC 2.95 I had to change .clear() to ="" but
since that is C-string assignment it should be just as fast.  You may
want to test it again to be sure though.
