With 20040208, I get the correct result (but this on powerpc-apple-darwin):
[zhivago2:~/src/gccPRs] pinskia% ./a.out
CSQRT(BVC)= ( 2.000000 , 1.000000 ) SQRT(BVC)= ( 2.000000 , 1.000000 )
CSQRT(BVC) - SQRT(BVC) ( 0.000000 , 0.000000 )
It looks right to me:
bvc = __complex__ (3.0e+0, 4.0e+0);
avc = csqrtf (bvc) - csqrtf (bvc);
