I can no longer compile C code linked to the Openwindows/xview-devel

fine in August 2015 but by mid September 2015 it was failing on the

I can reproduce this by compiling C code from the xview-examples

Thanks for reporting this issue, with reproduction steps and a fix!
I've rebuilt and uploaded updated xview 3.2p1.4-28-2 packages (32-bit
only, of course), with the additional patch [1] applied.
It's nice to know that someone is actually using the xview packages :)
Please let me know if there are any problems.

There now appears to be an issue with the definition of ucontext_t in
xview-devel with respect to Cygwin. If I manually edit
/usr/openwin/include/xview/base.h and change line 70 from undef to
#define SYSV_UCONTEXT
... the example above then compiles fine.
I cannot find any reference to recent Cygwin updates related to the
definition of ucontext_t

Yes, cygwin has only gained ucontext_t this year.
