gcov support in compile.el

[Masatake YAMATO]

I have written a regexp to handle a gcov output in compile.el.

2005-04-05  Masatake YAMATO  <address@hidden>

        * progmodes/compile.el (compilation-error-regexp-alist-alist): Add
        regexp for gcov.

2005-04-05  Masatake YAMATO  <address@hidden>

        * compilation.txt (symbol): Added gcov-file 
        gcov-bb-file gcov-never-called-line gcov-called-line .
