Bugzilla Bug 58827

Bochs 2.1.1 fails to compile with gcc-3.4.1. It builds fine with gcc-3.3.3-r6.

Reproducible: Always
Steps to Reproduce:
1. Use gcc34-x86-2004.2 profile.
2. emerge bochs

Actual Results:

very dubious fix

Now, I wouldn't trust myself for a second when it comes to patching this, but
from looking at the other functions it seems to me like the header RegparmsN(2)
is correct.
Someone with a clue has to take a look at it, though.

Compiles fine and seems to run, anyway =P.

looked over the fix and tried compiling it
its prob the right fix for the problem
ive not tried running it but it does compile

and if looked upstream my guess is would find a similiar fix

I don't think this fix is so dubious. I built bochs successfully and it's
running fine.

The fix looks okay to to me, since it is in Bochs CVS like that (although the
file will disapear in the next version).

the fix is correct, looks they made a typo.

Added in the ebuild, sorry for the delay
