I have previously compiled winex/cedega on my x86_64 within the 64 bit enviroment through the use of compiler flags and 'linux32' etc. Now I cannot compile any version, and the same errors are being returned as follows:

I seriously just don't know what to do, can someone please help.

I have the same, i think the struct vm86plus_struct does not exist on GCC 4.0.2 i'm using on Suse 10.0 64 bit
Is there any way to bypass this?
