Winchip was actually a cheap but slower Pentium MMX clone, I remember I 
had once to return my new PC, because it had this thingy installed 
instead of AMD K6 I paid for.

from kernel i386 arch Makefile:

cflags-$(CONFIG_MWINCHIPC6)     += $(call 
cc-option,-march=winchip-c6,-march=i586) 

cflags-$(CONFIG_MWINCHIP2)      += $(call 
cc-option,-march=winchip2,-march=i586) 

cflags-$(CONFIG_MWINCHIP3D)     += $(call 
cc-option,-march=winchip2,-march=i586) 

cflags-$(CONFIG_MCYRIXIII)      += $(call 
cc-option,-march=c3,-march=i486) $(align)-functions=0 $(align)-jumps=0 
$(align)-loops=0
cflags-$(CONFIG_MVIAC3_2)       += $(call cc-option,-march=c3-2,-march=i686)
