gcc version 2.96 20000717 (experimental) on TRU64/5.0A

[Lothar Wolf <syz at ecmwf dot int>]

Dear GCC-Team,

most likely I am not supposed to send a bug report for an experimental
version of gcc - but since I try to get gcc (the c++ part) compiled on
our AlphaStations for a long time now (many month) I hope you don't
reject it
and the report helps to get the best compiler around running on TRU64.

Following the recommendations of some of you I tried to use the most 
recent snap shots since 2.95.2 is not possible to compile on above
platform.
Compiling gcc (the c-part) was successfull without any problems!

Then using the just made gcc to create the g++ resulted in the following
error:


AlphaStation255, Compaq TRU64 5.0A, Firmware 5.70

alpha.ecmwf.int{/usr/local/devel/egcs-20000717}:501 --> gcc -v
Reading specs from
/usr/local/apps/lib/gcc-lib/alpha-dec-osf5.0/2.96/specs
gcc version 2.96 20000717 (experimental)

I am not sure whether I should include something else to this report so
please let me know

Thanks a lot for your attention
