Description: ecpg generating wrong code
Details:

I am maintaining code that uses ecpg. The following query was working with
the previous version of ecpg:

exec sql SELECT count(PortNum) INTO :cnt FROM Serial
WHERE ProjectId = :prjId and Enable = true;

After upgrading, the code is produced incorrectly. It now generates code as
follows:

{ ECPGdo(__LINE__, 0, 1, NULL, "select count ( PortNum ) from Serial
where ProjectId = ? and ensable = true ",
ECPGt_int,&(prjId),(long)1,(long)1,sizeof(int),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EOIT,
ECPGt_int,&(cnt),(long)1,(long)1,sizeof(int),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EORT);

The problem is the translation to ensable. This appears to be caused by the
file 'preproc.y' at the line:

| ENABLE_P { $$ = make_str("ensable"); }

Changing this to 'enable', fixes the problem.
