V: mingw64 can not compile on win7

[retsyo]

I am following your instruction in README.md, and try to compile on windows 7

$ gcc -std=gnu11 -w -o v.exe v.c  # Build it with
v.c: In function 'os__getexepath':
v.c:3601:22: error: invalid type argument of unary '*' (have 'DWORD {aka long unsigned int}')
   return tos(result, *GetModuleFileName(0, result, os__MAX_PATH));
                      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and

$ gcc --version
gcc.exe (Rev1, Built by MSYS2 project) 7.3.0

Windows 10 too, my gcc v8.1.0, error massage is the same.

Modify v.c as follows, and you can compile it manually gcc -std=gnu11 -w -o v.exe v.c

from

return tos(result, *GetModuleFileName(0, result, os__MAX_PATH));

to

return tos(result, GetModuleFileName(0, result, os__MAX_PATH));

[retsyo]

if we use os.getexepath() in V code, the following

return  tos ( result ,* GetModuleFileName ( 0 ,  result ,  os__MAX_PATH ) ) ;

will be generated.

I made PR for this: https://github.com/vlang/v/pull/783

PR #776 fixes the same but v.c needs to be updated too

Fixed.
