Hello, This patch addresses some general issues occuring for DOS-based filesystems. In some cases it might be better to replace the strrchr by lbasename, but I did this initial patch more mechanical. Of special interest is the code-change in gcov.c's function make_gcov_file_name. Most of the code is dead from Oct 2010. I modified it in a way that it has intended behavior. The cp/lex.c interface_strcmp() part I used filename_cmp for character comparision. Sadly there is no character comparision routine for filenames. So it might be an option here to implement directly within this option the file-system dependent code. For cleaness I avoid this for now. Changelog c-family/ 2011-03-14 Kai Tietz * c-ada-spec.c (compare_comment): Use filename_cmp instead of strcmp for filename.
