That is the number of conflicts encountered by the bison parser when it
processes file core/sql/parser/sqlparser.y. Here is how I get this information:
```
touch core/sql/parser/sqlparser.y
cd core/sql/nskgmake
gmake -j 4 -ks linuxdebug
```
Here is the current output:
```
../parser/sqlparser.y: warning: 73 shift/reduce conflicts [-Wconflicts-sr]
../parser/sqlparser.y: warning: 12 reduce/reduce conflicts [-Wconflicts-rr]
```
If you get a different (higher) number, then we would have to investigate
whether there are any potential problems with the new syntax.
