cannot convert `int (*)()' to `void*' in initialization - should not be an error

["Stuehlmeyer, Wolfgang" <Wolfgang dot Stuehlmeyer at softwareag dot com>]

Hello, 

i get multiple error messages of type 
"cannot convert `int (*)()' to `void*' in assignment" 
and 
"cannot convert `int (*)()' to `void*' in initialization" 

with the gcc 3.0 Compiler. (gcc-3.0-20010517.tar.gz) 

No error messages with the gcc 2.95.2 or 2.95.3. 

My project has 200 MByte of c/c++ source files. 50% of 
the binaries are build. I found this problem only. 



Best regards 
Wolfgang
