#375 C/DllSecur.c compilation fix for Mingw32 GCC

[Charlie Lin]

Small compilation patch:

When compiling with Mingw32 GCC, it complains:
../../../../C/DllSecur.c:69:50: error: cast between incompatible function types from 'FARPROC' {aka 'long long int ()()'} to 'BOOL ()(DWORD)' {aka 'int (*)(long unsigned int)'} [-Werror=cast-function-type]
69 | Func_SetDefaultDllDirectories setDllDirs = (Func_SetDefaultDllDirectories)

The attachted file fixes the issue by calling SetDefaultDllDirectories directly, instead of getting the function's address via getprocaddress.

[Anders]

This obviously changes the behavior of the program and it would refuse to run on Windows 7 without KB2533623 installed.

[Igor Pavlov]

Your code will not work in Windows XP system that don't support SetDefaultDllDirectories() function..

[Igor Pavlov]

I tried to google that problem.
And there is such suggestion there:

(void(*)())GetProcAddress

Please try it, and write here about results.
