Except mame is a most complex project and i have no idea where i
should change what, as there is no makefile anywhere near
imgui_draw.cpp

The things i could find are:

bash-5.0# grep -r std=c89 *
mame-mame0220/3rdparty/bgfx/3rdparty/meshoptimizer/Makefile:CFLAGS=-g
-Wall -Wextra -Werror -std=c89
mame-mame0220/3rdparty/bgfx/3rdparty/spirv-cross/CMakeLists.txt:

target_compile_options(spirv-cross-c-api-test PRIVATE -std=c89 -Wall
-Wextra)
mame-mame0220/3rdparty/genie/src/host/lua-5.3.0/src/Makefile:
$(MAKE) $(ALL) SYSCFLAGS="-DLUA_USE_C89" CC="gcc -std=c89"
mame-mame0220/3rdparty/lua/src/Makefile:        $(MAKE) $(ALL)
SYSCFLAGS="-DLUA_USE_C89" CC="gcc -std=c89"

Or do you mean the pkgsrc Makefile:

USE_LANGUAGES=          c99 c++

I guess i have to recompile it after these changes? Or can i still try
to link it with different settings now?

Unfortunately even with export PKG_DEBUG_LEVEL=1 i am not getting any
hint where it works on and which makefile is the culprit.

Anyway mame was a last resort and i thought it could work on sparc64
because it is a somewhat popular project.
But i don't really want to recompile it for 3 days on my Ultra 25 each
time i make one change to try.

As i need an Amstrad emulator, i will file segfaulting reports for
emulators/caprice32 and emulators/xcpc instead.
