Well ... this is a mixed C / C++ testcase (see the other file participating, gcc.dg/lto/pr54625-2_0.c). The C testsuite is the only one where the driver switches languages based on the file ending. Hmm, it seems at least the fortran frontend knows how to mix fortran and C. So if you really did not build the C++ compiler then we need, at least for lto.exp, a way to say dg-require-c++-frontend in the main file (thats the _0 one). Of course lto.exp misses a lot of other useful stuff ;) Btw, can we end up with the C frontend not built? Richard.
