It is outside the BLOCK_INPUT in x_create_frame, but inside another 
BLOCK_INPUT.

Installed cygwin, and tried to build.  Here is what I get:

#19 0x0114b433 in realize_x_face (cache=0x1b86140, attrs=0x82ec40, c=0,

Number 23:  Fdisplay_supports_face_attributes_p calls 
realize_basic_faces, which does BLOCK_INPUT before calling 
realize_default_face.

xbacktrace:

"replace-regexp-in-string"

Why does W32 have to do "call1 (Qface_set_after_frame_default, frame);"? 
 The other platforms (Mac and X) does not.  NOTE: I am not at all 
familiar with W32, there might be a good reason.
