--- Comment #12 from kargl at gcc dot gnu.org --- (In reply to dpozar from comment #11) > Thomas, > > that looks good. But I am not sure how to proceed ... > > dave Well, the first thing to do is to use either nm or objdump on the executable created from the code in comment #1 to determine where csqrtf() lives. If csqrtf() is from a Microsoft library, then we're done here and you need to contact Microsoft. If csqrtf() is from MingW's libm.a (or libm.so), then we're done here and you need to contact MingW. If csqrtf() is from libgfortran.a (or libgfortran.so), then you'll need to look at gcc/libgfortran/intrinsics/c99_functions.c.
