# ANSI C (the -Aa flag) nor can it produce shared libraries.  Thus we have

# I looked through the gcc.info and found this:
#   * GNU CC compiled code sometimes emits warnings from the HP-UX
#     assembler of the form:
#          (warning) Use of GR3 when frame >= 8192 may cause conflict.
#     These warnings are harmless and can be safely ignored.
