[Mono-dev] 2.4RC3 build problems (and code problems with the build)

  Here is what the gcc docs says about this warning:
-Wmissing-prototypes (C and Objective-C only)Warn if a global function is
defined without a previous prototype declaration. This warning is issued
even if the definition itself provides a prototype. The aim is to detect
global functions that fail to be declared in header files. I don't think
this could cause _any_ execution problems.
