How to make gcc 2.95.2 for HP-UNIX 11.00 work properly?

[sailnet.163]

Hello Gnu,

  After I install  gcc 2.95.2 for HP-UNIX 11.00 using install
file 'gcc-2.95.2-sd-11.00.depot', I try to test gcc work properly
or not.
  I wrote a c source file named 't.c' like this:
          #include <stdio.h>
          main()
          {
           printf("ok...\n");
          }

  But use the command 'gcc t.c' to compile file 't.c', it reports
a error message like this :
  'as: "/var/tmp/cc00iVOd.s", line 22: error 1052: Directive name
  not recognized - NSUBSPA'

  How can I make it work properly?

  Thanks!

Best regards,
