mingw: declare main()'s argv as const

Browse Source 
In 84d32bf (sparse: Fix mingw_main() argument number/type errors,
2013-04-27), we addressed problems identified by the 'sparse' tool where
argv was declared inconsistently. The way we addressed it was by casting
from the non-const version to the const-version.

This patch is long overdue, fixing compat/mingw.h's declaration to
make the "argv" parameter const.  This also allows us to lose the
"const" trickery introduced earlier to common-main.c:main().
