OK, I did run "gccxml -E" and "gcc -E". I can't figure what tweaks
need to be made.
Here's what "gcc -E" displays for the problematic line 214 of c++config.h:
# 42 "/usr/include/c++/4.4/complex" 3
# 1 "/usr/include/c++/4.4/alpha-linux-gnu/bits/c++config.h" 1 3
# 212 "/usr/include/c++/4.4/alpha-linux-gnu/bits/c++config.h" 3
namespace std
{
inline namespace __gnu_cxx_ldbl128 { }
}
And "gccxml -E" displays the same thing. The difference is that
there's a bunch of stuff (mainly declarations of functions named
__builtin_foo) from "/usr/share/gccxml-0.9/GCC/4.4/gccxml_builtins.h"
appearing before this.
Anyone have ideas?
Thanks,
-Steve
