Ahh - interesting. Thanks! So d_longdbl is more-or-less a pointless indicator, since the missing "uselongdouble" indicates that even though it existed, it was not incorporated at compile time.

Shame. Might have been nice to use - the uncertainty of major breakage dampens my desire to do the rebuild unfortunately... it's on an important business system...

    I think that such caution is unwarranted.
    If you do the rebuild with -Duselongdouble and the build still passes its tests, then there is no major breakage.
    As regards minor breakages (ie errors not picked up by the test suite) - they are just as likely to be present in the "double" builds as in the "long double" builds.

    Cheers,
    Rob
