Cannot compile with GCC 13: inline assembly constraint is incorrect

[vinz6751]

Hello
I'm using Cygwin64 with Vincent Rivière's GCC 13 Mintelf and the libcmini now fails to build. (I hadn't pulled it in a long time and I see it changed quite a bit)
hereis what I'm getting:

$ make VERBOSE=yes
mkdir -p build/. build/./objs
echo "CC build/./objs/strtoul_int.o"
CC build/./objs/strtoul_int.o
m68k-atari-mintelf-gcc -MMD -MP -MF build/./objs/strtoul_int.d -DSTDIO_MAP_NEWLINE   -Iinclude -c sources/strtoul_int.c -o build/./objs/strtoul_int.o
/tmp/ccbZta8H.s: Assembler messages:
/tmp/ccbZta8H.s:17: Error: operands mismatch -- statement `scs %a1' ignored
/tmp/ccbZta8H.s:40: Error: operands mismatch -- statement `st %a1' ignored
make: *** [Makefile:161: build/./objs/strtoul_int.o] Error 1

Obviously we can't do scs and st against an address register.
i think the "+g"(*overflow) constraint on line 28 and 41 should specify "d" rather than "g" to force the use of a data register.
