Build fails with 'asm' operand has impossible constraints

[juanitotc]

Describe the bug

Building dosbox-x-dosbox-x-v2024.07.01 using gcc-13.2 fails with:

In function 'ESFM_process_feedback',
    inlined from 'ESFM_generate' at esfmu/esfm.c:2222:2:
esfmu/esfm.c:1849:25: error: 'asm' operand has impossible constraints
 1849 |                         asm (

Using -fomit-frame-pointer seems to fix this

Steps to reproduce the behaviour

CPPFLAGS="-I/usr/local/include/ncursesw" LIBS="-lncursesw" CC="gcc -march=i486 -mtune=i686 -Os -pipe -fomit-frame-pointer" CXX="g++ -march=i486 -mtune=i686 -Os -pipe" ./configure --prefix=/usr/local --localstatedir=/var --enable-sdl2

find . -name Makefile -type f -exec sed -i 's/-g -std=gnu11  -O2/-std=gnu11/g' {} \;
find . -name Makefile -type f -exec sed -i 's/-g -std=gnu++14  -O2/-std=gnu++14/g' {} \;

make

Expected behavior

Builds without error

The code is Imported from https://github.com/Kagamiin/ESFMu so this issue should be reported and fixed there.
Maybe a bug of gcc-13 since gcc-14 and mingw lowend gcc7.3.0 is building fine.
