[gcc front end] add options

[charfi asma]

Hello,

I built a new gcc front end
I would like to use the -fopenmp options when compiling my source file
I could use the C front end options like -S -fdump-tree-all -O*, .... but when I 
use -fopenmp I get this error:

uml1: warning: command line option ‘-fopenmp’ is valid for 
C/C++/Fortran/ObjC/ObjC++ but not for  [enabled by default]

should I modify my lang-specs.h ? If yes what kind of modification ?

here is its content:

{".uml", "@uml", 0, 1, 0},
{"@uml", "uml1 %i %(invoke_as)", 0, 1, 0},
{"@uml",  "uml1 %i %(cc1_options) %{!fsyntax-only:%(invoke_as)}",
    0, 1, 0},


thank you very much

Asma
