* stab.def: Use __define_stab_duplicate rather than __define_stab

for duplicate entries N_BROWS and N_MOD2.
	* stab_gnu.h (__define_stab_duplicate): Define before including
	stab.def.

/* New stab from Solaris 2. This uses an n_type of 0, which in a.out files
overlaps the N_UNDF used for ordinary symbols. In ELF files, the
debug information is in a different file section, so there is no conflict.
This symbol's n_value gives the size of the string section associated
with this file. The symbol's n_strx (relative to the just-updated
string section start address) gives the name of the source file,
e.g. "foo.c", without any path information. The symbol's n_desc gives
the count of upcoming symbols associated with this file (not including
this one). */
