If there is a better way to do it, then by all means, that would be great. I have limited debug skills within cygwin. So, I simply googled gcc cdecl calling convention, to try to figure out just wtf could be wrong.
The mov 8(esp), eax were different than the unstable (which works). So I figured after the popa, that simply looking 4 bytes past esp was right, and it worked. But there certainly could be much better ways. If done before popa, wouldn't it be 0x24+4 ?
