(Did we ever determine the reason that not all functions are exported ?)

I think you pretty much answered that question when you quoted Jan Dubois. Which you might summarise as "because they can" on some platforms.

Try editing perl.h line ~3943 (5.8.8 build)

#  define PERL_CALLCONV __declspec(dllexport)
[download]

Without the above edit, perl58.dll from the AS817/5.8.8 distribution:

C:\test>pushd \AS817\perl\bin

C:\AS817\perl\bin>dumpbin /exports perl58.dll | wc -l
   1457

C:\AS817\perl\bin>dumpbin /exports perl58.dll | find "av_reify"

C:\AS817\perl\bin>
[download]

With the above change, perl58.dll(5.8.8):

c:\Perl\src\perl-5.8.8>dumpbin /exports perl58.dll | wc -l
   1995

c:\Perl\src\perl-5.8.8>dumpbin /exports perl58.dll | find "av_reify"
        627  272 00001000 Perl_av_reify
[download]

How many problems those extra 500 exports will fix I'm not sure, but I'm betting quite a few.

Whether it will work with 5.10 I'll tell you in about 1/2 hour.

Update: Seems to work similarly for 5.10 also:

[10:50:31.10]C:\Perl\src\perl-5.10.0>dumpbin /exports perl510.dll | wc
+ -l
   1993

[10:50:47.42]C:\Perl\src\perl-5.10.0>cd \Perl510\bin

[10:50:59.53]C:\Perl510\bin>dumpbin /exports perl510.dll | wc -l
   1387

And the (summary) output from nmake test looks 'normal':

Whether it will break anything anywhere, or is backwards compatible with 5.0 again I do not know.

And where it leaves all the shenanigins played out by embed.pl & regen_lib.pl and all the work that goes into maintaining embed.fnc, pp.sym, intrpvar.h, perlvars.h and thrdvar.h is another open question.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
