Thread: 7.4beta compile warning

Hi all, 
I had these during the compilation:

gcc -O2 -Wall -Wmissing-prototypes -Wmissing-declarations
-I../../../src/include   -c -o execScan.o execScan.c
execScan.c: In function `tlist_matches_tupdesc':
execScan.c:199: warning: unused variable `att_tup'


In file included from preproc.y:6278:
pgc.c: In function `yylex':
pgc.c:1386: warning: label `find_rule' defined but not used
/usr/include/ctype.h: At top level:
pgc.c:3367: warning: `yy_flex_realloc' defined but not used



Regards

Looks like you're the first person to build 7.4 without --enable-cassert
... or at least the first one who looked for warning messages.  Fixed.

These are flex's fault.  We could get around them but the work needed
is unreasonable.
