All,
Taking a walk through the source code is interesting.
Many of the internal processing subroutines assume the data are
floats (single precision).
The filtering portion of the code is a good example, bandpass,
lowpass, etc...
All of the subroutines involved in reading and writing assume a
specific size, and
many places in these routines assume a four byte floating point and
have this
value hard coded in. For example, the version number is at a
specific byte location

succeed if restarted. Why this occurs exceeds Andy's knowledge and my
own of Cygwin.
All of the build problems arise in libedit. I think that with an
automake/autoconf configuration step, sac2000 could simply look at the
build platform and omit libedit if an equivalent was av…
