Andreas> You need to set DECL_SOURCE_LOCATION now. To expand a little -- gcc has 2 possible internal representations of locations. The default changed to "mapped locations" in 4.3. In 4.4 we'll remove the old "expanded location" code entirely. The reason to use mapped locations is that they use less memory while also including information about the column number and include file sequence. >> I know I can decode the macros and deal with the "real" variables but >> what is the correct way to set the parm_decl members?
