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)
