I don't know of anyone who has tried to make SDL work with GNU Radio on 
Cygwin.

Might there be a problem if SDL is configured with -mno-cygwin and GNU Radio 
is not?  They may not agree on which include files and library functions 
(e.g., alloca.h and alloca) are available.  You may need to modify the 
configure file for SDL to fix this.
