conj: from multiple version to none ?

[Theodore Papadopoulo <Theodore dot Papadopoulo at sophia dot inria dot fr>]

It looks like the conj operator in complex.h (that seems to have been 
once defined twice according to the Changelog) has completely
disappeared.... And I do not understand why, since it seems to work 
perfectly for me. Is this some kind of parallel removal, or there is 
a deeper reason that I missed.

For the record, the following patch, restores a working conj for me 
(I also added the long double case).

ChangeLog:

2000-11-08 Theodore Papadopoulo <Theodore.Papadopoulo@sophia.inria.fr>

    * include/bits/std_complex.h: Re-enable conj. Added a version for
    long double.
