However, I'm not so sure as to where exactly the problem is any more. GCC_NO_EXECUTABLES is called for cross compilation way up around line 45 of configure.ac. So basically all the non-xcsafe-wrapped tests (like math, complex math, wchar_t, etc) that come after would appear to me obviously doomed. Mind you I could easily be missing something (which is why I cced Dan). Further, my problem might be separate from lv's. He shouldn't, afaict (again, I might be wrong), be being flagged as cross compiling, unless perhaps it's multilib related. BTW, is there a particular reason that mingw does not do the hardwired AC_DEFINES in crossconfig.m4 like so many other hosts, but rather the actual checks? That part of the workaround, judging by the surrounding entries, looks like it may be actually valid (that, or just a generally accepted hack for lack of anything better).
