so file must be created to work correctly in ASCII and EBCDIC system.
I'm having trouble following who said what in this discussion and what
if anything I'm being asked. So I hope the following helps.
charclass_invlists.h is one of 4 files that need to be modified
depending on the local platform's character set. The others are
l1_char_class_tab.h regcharclass.h and unicode_constants.h. All are
regen'd by scripts in the regen directory. Thus it is wrong to patch
these directly. Any such changes will be lost by the next regen, as the
comments at the top of each file say.
Also, there are 4 versions of each file, one for ASCII, and one for each
of the three EBCDIC code pages that Perl supports. Using
#ifdef EBCDIC ... #else
only gets two potential versions.
The approach use in 5.19 is to get miniperl compiled, and then use that
to regen each file for the current platform, before doing the full Perl
compile.
The git branch mentioned has the versions of each file suitable for
1047, though there are bugs in regcharclass.h concerning multi-char folds.

miniperl not correctly process scripts.
When analyzing found the incorrect processing of input data.
Two possible solutions the problem
first:
convert input data EBCDIC<>ASCII.
Converting input data is using macros NATIVE_TO_UTF, UTF_TO_NATIVE and
array PL_e2utf , PL_utf2e in file utfebcdic.h
But the converting is strongly scattered by the source code in one place and
had a double converting EBCDIC > EBCDIC .
second:
Changed array verification of input data in file charclass_invlists.h.
Can you share the changes you had to make, e.g. just simply "diff -u old
new" (or diff -c, depending on what diff tool you have available).

While you e.g. think about setting up an automated periodic build, one
simple thing to get the dialogue started would be that you show (email
to perl5-porters) these diffs you had to make for this file. (And
detail why exactly you had to do the diffs... to be able to build at
all? or to get more tests passing?)
