This is a bug report for perl from bulk88@hotmail.com,
generated with the help of perlbug 1.41 running under perl 5.27.9.
-----------------------------------------------------------------
[Please describe your issue here]
This is a 5.28 blocker.
Round #2 of https://rt.perl.org/Public/Bug/Display.html?id=133098 .
The patch "fix -DNO_MATHOMS build, mathomed syms were not removed from
perldll.def" breaks a WITH_MATHOMS (not a define) win32 build. I didn't
test on my main machine a WITH_MATHOMS (default) build before submitting
the patch but I tested today on another machine and got breakage.

--------------------------
These link errors bring up a question of what is a mathom-ed function
anyways.
The link error I see is because of
https://perl5.git.perl.org/perl.git/commitdiff/607313a19740cb756ab98d5e58e6040ea8c125d4
which used mathomed functions by their full name "Perl_to_utf8_title"
and not "to_utf8_title" which is redirected to a newer C func by preproc
in
https://perl5.git.perl.org/perl.git/blob/4273b0cccad37ddd85afb1abe763af2c6a6023a5:/utf8.h#l86
The top of embed.fnc
https://perl5.git.perl.org/perl.git/blob/4273b0cccad37ddd85afb1abe763af2c6a6023a5:/embed.fnc#l107
says that "m" symbols are not exported. Docs for "b" are ambiguous
https://perl5.git.perl.org/perl.git/blob/4273b0cccad37ddd85afb1abe763af2c6a6023a5:/embed.fnc#l67
Those 4 funcs are "ApbmdD" So "A" for public API (IE exported), "b"
for not avail on -DNO_MATHOMS, "m" for macro not a func. I thought I got
the permutation right in
https://perl5.git.perl.org/perl.git/commitdiff/1545ba5b042c208e23333479730479c0acd55325
"xmi" flags mean not exported. Previous KHW code that I was fixing
https://perl5.git.perl.org/perl.git/commitdiff/3f1866a8f6c7a9d70d0c8bb1b4f20d2db63756f1
so what is the definition of "b"?
I did a diff of my "fix -DNO_MATHOMS build, mathomed syms were not
removed from perldll.def" commit and cooked up this regex of now deleted
in WITH_MATHOMS symbols because they all have "m" flag but are also "b".

but grep.metacpan.org doesn't pull up anything unless I narrow the
search "to_utf8_title" (design bugs/search limit in seconds) and the
more trusty grep.cpan.me is down.
So again, I wonder, what is the definition of "b"? Is
https://perl5.git.perl.org/perl.git/commitdiff/607313a19740cb756ab98d5e58e6040ea8c125d4
correct and exactly how mathom symbols are supposed to be used in
fallback mode and "b" always means exported from binary unless
NO_MATHOMS? or does "m" always mean "never exported" regardless of any
other build choices and XS-Apitest and any CPAN code is wrong?
A decision must be made for 5.28.
