             Bug #: 56436
           Summary: Documentation states restriction that's not enforced
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: simon@pushface.org

Patch to remove documentation inconsistency

gcc/ada/projects.texi states, for Spec_Suffix, that (amongst other rules)

It cannot start with an alphanumeric character
It cannot start with an underscore followed by an alphanumeric character

Neither of these rules is enforced, in other words this is legal:

project Prj is
   package Naming is
      for Spec_Suffix ("Ada") use "_s.ada";
      for Body_Suffix ("Ada") use "_2.ada";
   end Naming;
end Prj;

There is at least one user who uses _s.ada, _b.ada, so it should be appropriate
to remove the stated restriction as in the attached patch.
