Thanks for Kai Ruottu's detailed explaination. The method of adding a new target
template seems too professional for me.
Maybe so, therefore here is the diff for the new 'alpha*-dec-osf*'
target/host template in 'gcc-4.0.3/gcc/config.gcc' :

The extra 'alpha/osf12.h' and 'alpha/osf2or3.h' config headers must be
copied from
the gcc-3.2.3 into gcc-4.0.3. And after that you could try to configure
and build the
'alpha-dec-osf1' targeted GCC. And then "see from where the smoke rises"...
The previous was only a quick edit and maybe something was forgotten.
The goal
was that the earlier 'osf[45]' support would remain as it was, but the
new 'osf[1-3]'
"support" would be added by simple "cut and paste" methods...
I really don't know how radical changes there could be between OSF1 -
OSF[45] and
if they could spoil the previous simple scheme. The real "professionals"
could tell it
but it is however easy to see what happens if one tries to build GCC for
OSF1.... The
previous only lets the target name 'alpha-dec-osf1' being accepted and
tried.
With the 'alpha/osf2or3.h' I did some editing because trying a
crosscompiler, the
'real code' in it was made to be :
----------------------------------- clip
----------------------------------------
/* In OSF 2 or 3, linking with -lprof1 doesn't require -lpdf. */
#undef LIB_SPEC
#define LIB_SPEC "%{p:-lprof1} %{pg:-lprof1} %{a:-lprof2} -lc"
/* As of OSF 3.2, as still can't subtract adjacent labels. */
/* #undef TARGET_AS_CAN_SUBTRACT_LABELS */
/* #define TARGET_AS_CAN_SUBTRACT_LABELS 0 */
/* The frame unwind data requires the ability to subtract labels. */
/* #undef DWARF2_UNWIND_INFO */
/* #define DWARF2_UNWIND_INFO 0 */
----------------------------------- clip
----------------------------------------
The 'alpha/alpha.h' seemed to define the first commented thing as
'TARGET_GAS', ie.
if using GNU as, "TARGET_AS_CAN_SUBTRACT_LABELS" is true... Maybe the latter
should be defined similarly. So I expected these already being defined
"right"....
Okeydokey, my own try stopped with :

The binutils used were "2.14.90.0.8 20040114". Continuing my try after
updating
these old ones into "2.16.91" or something a little newer ones...
