compat/mingw.[ch]: Change return type of exec functions to int
The POSIX standard specifies a return type of int for all six exec functions. In addition, all exec functions return -1 on error, and simply do not return on success. However, the current emulation of the exec functions on mingw are declared with a void return type. This would cause a problem should any code attempt to call the exec function in a non-void context. In particular, if an exec function were used in a conditional it would fail to compile. In order to improve the fidelity of the emulation, we change the return type of the mingw_execv[p] functions to int and return -1 on error.
