           Summary: Incorrect evaluation '=' in GNATPREP
           Product: gcc
           Version: 4.5.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ivansavvateev@yandex.ru


GNATPREP evaluates incorrectly an expression contains two integer symbols. For
example, when I define:

SYS_MODE_PCP := 1
SYS_MODE := SYS_MODE_PCP

and try to preprocess:

#IF SYS_MODE = SYS_MODE_PCP
      TCB        : P_TCB;
#END IF; 

I get after preprocessing:

--! #IF SYS_MODE = SYS_MODE_PCP
--!       TCB        : P_TCB;
--! #END IF;

although the condition is true.
