On FreeBSD/Alpha, all 89 tests pass.
I get this build warning though:
gcc -pipe -O -Wall -Wmissing-prototypes -Wmissing-declarations -I. -I../../.
./src/include -c -o gram.o gram.c
In file included from gram.y:7725:
scan.l: In function `yyerror':
scan.l:583: warning: int format, different type arg (arg 5)
