Nope, 2.6 still has the SEH misuse bug.  But if you want to rebuild from a
git repository, my patches are now available to fix the SEH handling
(although I recommend building against cygwin snapshot 20090722 or newer;
building against cygwin 1.7.0-51 will detect that si_addr is still broken,
and pick up baggage related to cygwin 1.5 but not necessary for the latest
cygwin1.dll).  I only lightly tested a shared library with my patches.
Although the testsuite passed while using the shared library, I am still
wondering if there could be a problem at program shutdown if the shared
library is removed from memory without modifying its SEH handler back to
cygwin's handler, but I don't have any test case that provoked that scenario.

$ git pull git://repo.or.cz/libsigsegv/ericb.git master
