+workaround for lame stack packing on i386 ...
+
+	- build gcc with -Os (crtfastmath.o to be specific)
+	- crtfastmath.o is installed into gcc libdir
+	- run gcc with -ffast-math and get crtfastmath.o linked in
+	- resulting compiled app segfaults due to init code in
+	  crtfastmath.o that has mis-aligned structure on stack
+
+http://bugs.gentoo.org/147020
+http://gcc.gnu.org/PR28621
+
+this is supposed to be fixed in current 4.1 branch, but i'm unable to get
+the fix to work so until i can figure out what i'm doing wrong, we'll use
+this workaround for now.
