      sparse: Fix mingw_main() argument number/type errors · 84d32bf7
      Ramsay Jones authored
      Sparse issues 68 errors (two errors for each main() function) such
      as the following:
            SP git.c
        git.c:510:5: error: too many arguments for function mingw_main
        git.c:510:5: error: symbol 'mingw_main' redeclared with different type \
          (originally declared at git.c:510) - different argument counts
      The errors are caused by the 'main' macro used by the MinGW build
      to provide a replacement main() function. The original main function
      is effectively renamed to 'mingw_main' and is called from the new
      main function. The replacement main is used to execute certain actions
      common to all git programs on MinGW (e.g. ensure the standard I/O
      streams are in binary mode).
      In order to suppress the errors, we change the macro to include the
      parameters in the declaration of the mingw_main function.
      Unfortunately, this change provokes both sparse and gcc to complain
      about 9 calls to mingw_main(), such as the following:
            CC git.o
        git.c: In function 'main':
        git.c:510: warning: passing argument 2 of 'mingw_main' from \
          incompatible pointer type
        git.c:510: note: expected 'const char **' but argument is of \
          type 'char **'
      In order to suppress these warnings, since both of the main
      functions need to be declared with the same prototype, we
      change the declaration of the 9 main functions, thus:
          int main(int argc, char **argv)
