Thank you very much for your analysis of the problem.
Extra directory for header files is determined in gcc
via compiler::*cc* variable. Actually this is just full
gcc command with all parameters which is used by lisp
compiler. The fix for it is in init-cl.lisp file.
This fix was erroneous in the trunk (it was OK in 5.12 branch).
I think that I fixed that problem in trunk and in the 5.13 branch.
So, it should be OK in next RC.
