Adding HURD/Alpha configuration to build?

[Andrew M. Miklic]

I am trying to add support for a HURD/Alpha (alpha-gnu?!?) build 
configuration to gcc, but the only file I could find that seemed to 
actually control "*-gnu" targets was gcc/config.gcc (there was a 
documented section there which seemd to show what to do to support 
HURD-based architectures--x86 and mips are already supported, 
apparently, according to the comments and the configuration statements). 
I tried to make the appropriate changes to support alpha-gnu in this 
file (following the leasd of the x86 and mips statements), then tried 
the following configurations:

    ./configure --target=alpha-gnu
    ./configure --target=alpha-unknown-gnu
    ./configure --target=alphaev56-gnu
    ./configure --target=alphaev56-unknown-gnu

but configure still complains about all of these being unsupported 
targets--does anyone know how to add support for an architecture to a 
HURD build configuration ?


Sincerely,
