After patching libgfortran/configure the code of
libgfortran/intrinsics/c99_functions.c was used. But this code has still a
problem seen with the following fortran code
program test
complex cres1, cres2
cres1 = -(4,0)
cres2 = sqrt(cres1)
print*,'cres1=',cres1, 'cres2=',cres2
cres1 = (-4,0)
cres2 = sqrt(cres1)
print*,'cres1=',cres1, 'cres2=',cres2
end
This requires also corrections in libgfortran/intrinsics/c99_functions.c .
The patches I have made compared to gcc-rev-107187 from gcc's SVN you will find
