Re: [Patch 0/3] Remove duplicate type declarations in MdePkg and CryptoPkg

["Michael D Kinney" <michael.d.kinney@intel.com>]

Liming,

GCC can detect redefinition of same type.

--------------------
typedef int foo;
typedef int foo;

int main (int argc, char *argv[]) {
  return 0;
}
--------------------
gcc a.c -Wpedantic -std=c99

a.c:2:13: warning: redefinition of typedef ‘foo’ [-Wpedantic]
 typedef int foo;
             ^~~
a.c:1:13: note: previous declaration of ‘foo’ was here
 typedef int foo;
             ^~~
