--- Comment #7 from dmalcolm at gcc dot gnu.org --- (In reply to Andrew Pinski from comment #6) > Let's keep this open for a fix includes solution. Does anything in gcc's bootstrap or testsuite actually use dejagnu.h? (other than my jit.exp on the jit branch, and I've fixed that now by adding -fgnu89-inline) It seems to be that this is more an issue for both: (A) DejaGnu upstream (where I've reported it), and (B) GCC release notes, for some kind of 5.0 porting guide (i.e. "what does an end-user need to know about the gnu11 change?")
