Bug Summary and Steps to Reproduce

Bug Summary: C/C++ is reporting errors in a source project that uses GCC's _Decimal128 implementation.

Steps to reproduce:

Create new project containing single file on remote

int main (int argc, char **argv) {
  _Decimal128 v;
  v=1.25DL;
  return (int)v;
}

Result is two errors for the source file:

identifier "_Decimal128" is undefined extra text after expected end of number

Expected behavior:
