egcs-2.91.58: compiler-error on aix 4.2.1

[michael becker]

  hi,

  i tried to compile emacs-20.3 on aix 4.2.1.  

  egcs-version: 

Reading specs from 
/usr_local/lib/gcc-lib/powerpc-ibm-aix4.2.1.0/egcs-2.91.58/specs
gcc version egcs-2.91.58 19981101 (egcs-1.1.1 pre-release)


   script-output:

    (nil))

   --- script end


if i change CFLAGS="-g"  to  CFLAGS="-O"  egcs compiles src/fileio.c.
