drh 01f75f2d68 In the lemon parser generator, change all hashes to unsigned to avoid 
potential problems with signed integer overflow.

drh 8ba0d1cbca In Lemon, when comparing the output to the *.h file to see if it has changed, 
make sure that the proposed new output and the preexisting output are the
same size before deciding that they are the same.

SQLite.

drh 7dd1ac600e Fix a bug in lemon in computation of which non-terminals can generate an 
empty string.  This bug and the fix make absolutely no difference for the
grammar used by SQLite, but it can make a difference when lemon is used
in other grammars.

icculus d191282111 Added option to not clip error output. 
This is useful for IDEs and other tools that benefit from full path
information, so they can jump directly to the error line in the source code.

icculus f5ad824071 Delete output files if this is a failed run. 
Otherwise, the fail will stop a Makefile from progressing, but if you
immediately run the build again, Make will think the output files are up to
date, since they are newer (albeit incomplete/incorrect).

drh c53eed1703 Change lemon so that it does not generate yytestcase() macros on destructor

drh 8a415d3743 The lemon parser generator now inserts yytestcase() macros on reduce action

is a no-op by default but can be set to something more useful inside
of %include. (CVS 6755)
