// GROUPS passed templates
// Bug: g++ emits template instances when it shouldn't.
// Special g++ Options: -g -fno-inline -Wno-deprecated -fexternal-templates

// We mark this XFAIL because we can't test for expected linker errors.
// If we get an XPASS for this testcase, that's a bug.

// Suppressed-instantiation tests like this are known to break on
// Cygwin, because of the MULTIPLE_SYMBOL_SPACES stuff.  This is OK.

// (OK) excess errors test - XFAIL *-*-*
