The vast majority of Vladimir's patch was fix something call Mixed Declarations
eg:

      int i = 0 ;
      printf ("%d\n", i) ;
      int j = 1 ;

You can disallow these mixed declarations in C99 code using -Wdeclaration-after-statement
which is probably better than downgrading everything to C89 for comaptibilty
with one compiler.

People should also be aware than even though VS2013 claims some C99 compatibility
my recollection is that it still does not provide a standards conforming snprintf
implementation.
