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.

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

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