(cough)

I was a bit too soon reporting the sparc-sun-solaris2, two
attempts have died with stg_ap_v_ret. Same result sparc-*-openbsd.

Here's an updated list:

+-----------------+--------------------+---------------------------+
|     HOST        |      TARGET        | Unregisterised bootstrap  |
+-----------------+--------------------+---------------------------+
| i386-*-openbsd  | i386-*-openbsd     |          YES              |
|                 | i386-*-freebsd     |          YES              |
|                 | i386-*-linux       |          YES              |
|                 | i386-*-solaris2    |          YES              |
|                 |                    |                           |
|                 | sparc-sun-solaris2 |      stg_ap_v_ret         |
|                 | sparc-sun-openbsd  |      stg_ap_v_ret         |
|                 |                    |                           |
|                 | m68k-apple-netbsd  | boots libs, dies in gmp   |
|                 |                    |                           |
|                 | alpha-dec-osf3     |      in progress          |
+-----------------+--------------------+---------------------------+

Is there an endianess thing here? What is the endianess of the
amd64 and the powerpc? Are than any tricks I can try?
