* doc/FileSystem.3: CONSTified Tcl_FSFileAttrStringsProc
* generic/tclFCmd.c: and tclpFileAttrStrings. This allows
* generic/tclIOUtil.c: FileSystems to report their attributes
* generic/tclTest.c: as const strings, without worrying that
* unix/tclUnixFCmd.c: Tcl modifies them (which Tcl should not
* win/tclWinFCmd.c: do anyway, but the API didn't indicate that)
* generic/tcl.decls
* generic/tclDecls.h: regenerated
* generic/tcl.h: make sure that if CONST84 is defined
as empty, CONST86 should be defined
as empty as well (unless overridden).
This change complies with TIP #27
