Bug of complex.h ??

[WeiCheng (Leon) Wang]

Hi,
  I am not sure if this is a bug of the libstdc++2.90.5 for complex.h
while I am rebuilding it on an alphaev56-dec-osf4.0d machine with
existed egcs-2.91.66 (egcs1.1.2) c++ complier and old libstdc++2.90.0.
The error messages are list as below :

So, I tried to regenerate the more detail error messages by following
the bug report instructions and attach the complex.ii with this email:
