Hi,
thanks to Austin i could work on our sparc port and it seems i have it it a workable state,
the remaining problem is that somehow the plt entry to libwine is fixed up wrong.
I know most people on the list don't know much about sparc, so wild guesses are all i want.

--- /snip (also available as http://pastebin.com/JFN2w6q2 if bad format) ---
it crashes (SIGSEGV) at wine_dbg_log at plt (0xf66a8988) in imm32.dll.so
(if i remove the TRACE from DllMain it continues to crash with other libwine functions in winex11)
033dfa34 seems like a wrongly fixed up opcode to me. What do you guess?
Should i file a bug? where?
