G'day,
Antonio mentioned he was hoping to release an updated set
of packages for the Tecgraf scientific/technical tools --
particularly IUP.
I've decided to work on preparing "lglicua-0.1-alpha7"
release to go on SourceForge, that picks up the latest tools
such as Lua 5.4.4 and LuaRocks 3.9.1, as well as expanding
the GNU/Linux platforms that it handles (including kernel
6.x,y, and both gcc-11.x and gcc-12.x).
When I looked at the diagnostic output, I noticed
significant duplication, due to a few header files that
contained warnings, being #included by multiple C/C++
sources.
So, I've reworked the script to remove duplicates. The
result is that some report summaries are less than half
their former size.
---------
Attached are the warnings for IM-r820, under gcc 12.
(Others will follow: pdflib7, ftgl, cd, iup.)

cheers,
