 HI,
 I have tried to build gdc with gcc 4.2.2 .
 I know it is not support yet.I just want to have a try.

The gcc internals have changes between 4.1 and 4.2, this was in 4.1's
tree.h:

 /* Construct various types of nodes.  */
=20
 extern tree build (enum tree_code, tree, ...);
 extern tree build_nt (enum tree_code, ...);
=20
 #if GCC_VERSION >=3D 3000 || __STDC_VERSION__ >=3D 199901L
 /* Use preprocessor trickery to map "build" to "buildN" where N is the
    expected number of arguments.  This is used for both efficiency (no
    varargs), and checking (verifying number of passed arguments).  */
 #define build(code, ...) \
   _buildN1(build, _buildC1(__VA_ARGS__))(code, __VA_ARGS__)
 #define _buildN1(BASE, X)       _buildN2(BASE, X)
 #define _buildN2(BASE, X)       BASE##X
 #define _buildC1(...)           _buildC2(__VA_ARGS__,9,8,7,6,5,4,3,2,1,0,=


 #define _buildC2(x,a1,a2,a3,a4,a5,a6,a7,a8,a9,c,...) c
 #endif



And here is what there is in 4.2's:

 /* Construct various types of nodes.  */
=20
 extern tree build_nt (enum tree_code, ...);



Looks like buildN are called =E2=80=9Cby hand=E2=80=9D in objc and fortan f=
ront-ends.

There are also in ChangeLog-2003:

2003-05-17  Kaveh R. Ghazi  <ghazi caip.rutgers.edu>

        * builtins.c (validate_arglist): Eliminate libiberty VA_ macros,
        always use stdarg.
        [...]
        * tree.c (build, build_nt, build_function_type_list): Likewise.


Please let us know if you get something working, it would be so nice
if gdc were ported to gcc-4.2. :-)


Have a nice day,

Arthur.
