           Summary: jacidl fails when having '#' character inside string in
                    included idl files
           Product: JacORB
           Version: 3.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: IDL compiler
        AssignedTo: jacorb-bugs at lists.spline.inf.fu-berlin.de
        ReportedBy: kuba.gasiorowski at computaris.com


Hello,
according to the IDL standard, the #... is interpreted as a preprocessor
directive only if is the first character (excluding spaces) in the line:
'Lines beginning with # (also called "directives") communicate with this
preprocessor. White space may appear before the #.'
jacidl fails when processing files which contains the string like:

const string<100> structs1_str = "@(#)base0 2012/10/17" ;

in nested IDL files (in single files error does not occur), trying wrongly
interpret the string after '#' as preprocessor directive:

I haven't found any workaround except of removing '#' from the strings.

Sample IDL files to reproduce the error attached.
