Sorry about that, this error didn't show up with the compiler I used.
I just built one straight from mainline and could reproduce the error.
Apparently, expressions like this are not legal?

        (char *) something = NULL;

Anyway, I fixed the immediate problem by expanding the PST_PRIVATE
macro into its actual definition, but without the cast. That should
allow you to build again.

        * dwarf2read.c (dwarf2_create_include_psymtab): Fix build
        failure detected by recent versions of GCC.
        (psymtab_to_symtab_1): No longer use the PST_PRIVATE macro
        to be consistent with the usage in dwarf2_create_include_psymtab.

Checked in mainline.
