I have a question about this.
The b2 file contains: SOURCES = ... codecvt_null
which means that this code is included in the library "boost_serialization". Hence it should not be necessary in the library boost_wserialization. So it seems to me that making this change would mean the code is included twice. Perhaps the code IS in boost_serialization but there might be some issue with visibility setting which prevents the linking to the code in boost_serialization. Or ... I don't know. Needs more investigation.
There is following error without this patch:
[build] ld: ......./libboost_wserialization-gcc112-mt-d-1_69.a(basic_text_wiprimitive.o): in function `boost::archive::codecvt_null<wchar_t>::codecvt_null(unsigned long)':
[build] ......./boost/archive/codecvt_null.hpp:97: undefined reference to `vtable for boost::archive::codecvt_null<wchar_t>'
And apparently there was already a patch for this problem, but it was rejected: https://github.com/boostorg/serialization/pull/42
I can provide the exact linker error and/or reproducible example, if necessary.
(This is a very old bug, present in boost-1.69 (and possibly before), I had to patch the boost for several years.)
