+Subject: [PATCH]        * Makefile.in (vis_hide, gen-hide-list): Do not make
+ definitions    depend on --enable-shared. 
+ ($(lib1asmfuncs-o)): Use %.vis files independent of 
+ --enable-shared.       * static-object.mk
+ ($(base)$(objext), $(base).vis) 
+ ($(base)_s$(objext)): Use same rules for visibility
+ handling as in         shared-object.mk.
