+Valgrind <http://valgrind.org/> is also highly recommended, if
+Valgrind supports your architecture.

+Bison is written using Bison grammars, so there are bootstrapping
+issues.  The bootstrap script attempts to discover when the C code
+generated from the grammars is out of date, and to bootstrap with an
+out-of-date version of the C code, but the process is not foolproof.
+Also, you may run into similar problems yourself if you modify Bison.
 
 Only building the initial full source tree will be a bit painful,
 later, a plain `cvs update -P & make' should be sufficient.

-* Troubleshooting
-
-Unfortunately the current Gettext still does not include all the
-needed tools so that the bootstrapping always perform successfully.
-
-If you experience problems, I suggest the following:
-
-1. Do a regular CVS checkout
-
-2. Fetch a recent tarball in:
-   ftp://alpha.gnu.org/gnu/bison/
-
-3. Extract it
-
-4. Override the content of your checkout with the content of this
-   tarball, i.e.:
-   cp -r bison-1.875c/* bison-cvs
-
-5. Proceed on ./configure && make etc.
