compiling problem pinpointed

Compilation fails because builtin_compiler
seg. faults.

In glcpp-parse.y (and .c)
In add_builtin_define()
The "list" is 80d4880 prior calling
  _define_object_macro()
In _define_object_macro() the list is, as
"replacements", 80aad5c

Does not look a simple coding bug but a major
compiler failure. I start fiddling the compiler
flags now.
