>How-To-Repeat:
See above.
>Fix:
A tell-tale seems to be:

  src/3rdparty/opennurbs/CMakeFiles/OpenNURBS.dir/cmake_pch.hxx.gch

Unless it has come to mean something else, the "pch" in the above
file may mean "pre-compiled header" and these have frequently been
a problem on NetBSD/i386.

In the past, such situations were worked around by disabling pre-
compiled headers, but I'm not sure how that's done with 'cmake' in
the mix.

 Same problem seen on netbsd-10/i386 (10.1_STABLE from sources as of
 202510030012Z).)

 It looks like pre-compiled headers are to blame, but grepping the qcad
 sources I didn't find anything.

 The cmake docs mention this:
 https://cmake.org/cmake/help/latest/prop_tgt/DISABLE_PRECOMPILE_HEADERS.html#prop_tgt:DISABLE_PRECOMPILE_HEADERS
 but they refer to properties documented here
 https://cmake.org/cmake/help/latest/command/target_precompile_headers.html
 that I haven't seen in the qcad code.
