[RFA] More file-name related fixes

["Eli Zaretskii" <eliz@is.elta.co.il>]

(Elena should love this, since it eradicates a few more STREQ's ;-)

I'm seeking approval for the following patches for symtab.c which make
handling if file names in symtabs and psymtabs more portable:

2001-05-02  Eli Zaretskii  <eliz@is.elta.co.il>

	* symtab.c (lookup_symtab_1, lookup_partial_symtab): Use basename
	instead of non-portable search for `/'.  Use FILENAME_CMP instead
	of STREQ, to account for case-insensitive filesystems.
	(top-level): #include "filenames.h".
