--- Comment #2 from Jaroslav Fojtík <JaFojtik at seznam dot cz> --- May be that I did something wrong, but this code worked for 20 years without any problem. It has been also tested unded Borland and VisualStudio without any notable problem. I have noted problem only for GCC 14. You can see that 13.2.1 has no problem on compilefarm 27. /home/jara/mintest> A<<<struct>>> (c)1998-2024 Jaroslav Fojtik This program tests the struct.c library ***LO_ENDIAN defined*** ***NATIVE access*** Testing struct manipulation ..............
