gdb 4.17 on powerpc-ibm-aix4.2.1.0 fails

[KRUMPOLEC Martin <krumpo@pobox.sk>]

Env: gdb 4.17 on our PowerPC AIX 4.2,

Hello,

  I have this test program:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%s\n", argv[0]);
  return 0;
}

  I compile it either by gcc or vendor's cc using
  following commands: (gcc = egcs 1.1 or gcc 2.8)

cc -g -o test test.c
gcc -g -o test test.c
gcc -ggdb -o test test.c

  But when I try tu start gdb on result, it always fails:

If in fact that file has symbols which the mapped files listed by
"info files" lack, you can load symbols with the "symbol-file" or
"add-symbol-file" commands (note that you must take care of relocating
symbols to the proper address).

  Am I doing something wrong, or I have found bug ? 
  (gdb was build in obvious was = ./configure && make install)

Thank you very much
