But there is a compilation error if compilation is attempted without all/any threads? IIRC, there is an #error directive to that effect in ecl.h

In any case, could you share configuration flags?

sagemath (sagemath.org) uses ecl 16.1.2 to compile and run Maxima (and not only it) on Cygwin, so it is certainly possible. we turn threads off, however.
As well, we add -D_GNU_SOURCE to C and CXX flags.

Hello
I am trying to build and use ECL on windows machine under cygwin environment
However, evter it is built, there arises a problem when i try to compile any lisp files, for example when running examples/build/readme.lisp
Inspecting with gsb gives the picture of stack overflow on handling some exception across threads, overflow occuring in the bad case of circular calls to acquiring thread-local data (pthreads_getspecific) and processing error message from failure of it.

is there recommended configuration for cygwin that would allow to overcome that kind of problem? Alternatively, what data exactly are needed for a full bug report? I would gladly provide everything relevant
