Later on in Robert's softfloat patch for gcc 3.3.2 in crosstool
0.28rc28, you find this:

-#define TARGET_DEFAULT (ARM_FLAG_APCS_32 | ARM_FLAG_MMU_TRAPS)
+#define TARGET_DEFAULT \
+       ( ARM_FLAG_APCS_32 | \
+         ARM_FLAG_SOFT_FLOAT | ARM_FLAG_VFP | \
+         ARM_FLAG_MMU_TRAPS )

So now which is the default, FPA or VFP?

I'm confused :-/
