It is.  There's a configure option "--ignore-absence-of-libsigsegv".  But there 
are more serious problems, affecting both the 32-bit and 64-bit versions.  (So 
even just rebuilding clisp for 32-bit Cygwin will take some work.)  The problem 
is that lisp.exe, which is built and used in the course of trying to build 
clisp.exe, crashes with a SEGV shortly after it's started.

My reason for looking at this was that clisp is needed for building xindy, an 
optional component of TeX Live.  I did successfully build clisp in the 32-bit 
case four years ago, but I can't any more.  My guess (untested) is that this is 
because the location of the heap has changed since then, and maybe the source 
code makes unwarranted assumptions about memory layout.

It's a shame that Reini isn't available to help with this.
