Summary: libquadmath: List __complex128 and constants in the
.texi file
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: documentation
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: burnus@gcc.gnu.org
libquadmath.h contains a typedef and several macros (constants), which should
be listed in the documentation.
typedef _Complex float __attribute__((mode(TC))) __complex128;

I don't understand the intent of this PR. We
do not list the analogous constants for float, double,
and long double anywhere in the Fortran manual.
Why single out libquad constants?

Note: The PR is about libquadmath and libquadmath.texi and not about the GNU
Fortran manual.

See the Subject line. Specific this part --> [Bug fortran/47295].
If there isn't a libquad tag, then use Other as in [Bug Other/47295].
