Compile Ruby 1.8.4 on HP-UX 11

When I run make (we are using cc not gcc) I receive:

make

cc -Ae -s -O +Z -DRUBY_EXPORT -DYYMAXDEPTH=300 -I. -I. -c parse.c
cc: “parse.y”, line 4439: warning 527: Integral value implicitly

make: *** [parse.o] Error 1

Any suggestions?

I think you will get better results with gcc and gnu make.
