 Installing the target C library belongs to this phase. How else the GCC
build could fix the target headers for GCC and check what the target libraries
have or have not?

 The '--with-headers=<something>' means that you really have the target headers
copied into this location ! Ok, using it in this case just as the previous
option should be vain, here the value given to it is even totally wrong. But
what we are to understand the thoughts of the high GCC priests, or any other
weird theology? Quoting the "GCC Internals" manual for 3.4 :

  A cross compiled GCC runs fixincludes on the header files in
  '$(tooldir)/include'. (If the cross compilation header files
  need to be fixed, they must be installed before GCC is built.
  If the cross compilation header files are already suitable
  for GCC, nothing special need be done).

The GCC manuals tell something and the GCC build does something else but still
everything is just as it should be and has always been such. Sigh...

>>--enable-languages=c --disable-shared --disable-threads --with-newlib

 Why not C++ and other languages required?  AIX 5.1 doesn't use newlib and
therefore the last option is badly wrong !

 These four last options tell where your AIX5.1 target binutils and C library
SHOULD be preinstalled !

 The AIX5.1 headers should include these...

 What on earth you have done? How the 'time.h' in the target headers could
try to #include the 'linux/types.h' ?

 If one should put diesel into the tank and one puts 95 octane, a really big
bang boom can be the result... Or 'fairytales' about what happened when one
innovative engineer once put Fairy into a dish washer machine will be told...

 Here you can see what happens when one uses Linux headers instead of AIX
headers... Once tried using Fairy (British hand-wash liquid) in a dish-washer
just like the technical director from the near steel factory and we both are
not allowed by our wives to wash any dishes any more... How sad indeed ! What
was your goal in this fairytale?  That you would not be asked to build any
GCCs any more? :-)
