...containing replacements for global operator new/delete (that can be linked
into executables), but which is no longer used.  The mail thread starting at
<https://lists.freedesktop.org/archives/libreoffice/2012-March/028690.html>
"operator new no longer routes through rtl_AllocMemory in libsalcpprt under
gbuild link rules" has the details of how this was used on some platforms (but
not on others) before the switch to gbuild, and has been "lost" ever since---but
apparently a loss not mourned much over the years.

For the SDK, c5f97428 "INTEGRATION: CWS jsc3:
#i62434# copy libsalcpprt.a" added the library (under Linux) and
6db9c5af "INTEGRATION: CWS jsc3: #i62434# extend
link options for executbales to link libsalcpprt.a, LINUX only" added its use to
odk/settings/settings.mk, but fc0ca57f
"INTEGRATION: CWS jsc21" removed that use again (for no documented reason).  So
this is an incompatible change, but unlikely to actually affect any users of the
SDK.
