// Modified from the Chromium original:

// symbols (or their output) and manipulating preprocessor symbols
// that define strings.

// This is not very useful as it does not expand defined symbols if
// called directly. Use its counterpart without the _NO_EXPANSION
// suffix, below.
#define STRINGIZE_NO_EXPANSION(x) #x
// Use this to quote the provided parameter, first expanding it if it
// is a preprocessor symbol.
//
// For example, if:
// #define A FOO
// #define B(x) myobj->FunctionCall(x)
//
// Then:
// STRINGIZE(A) produces "FOO"
// STRINGIZE(B(y)) produces "myobj->FunctionCall(y)"
#define STRINGIZE(x) STRINGIZE_NO_EXPANSION(x)
