GCC commit r15-5326-gf242f79b8afe defaults to -std=gnu23, and in C23
void foo() means void foo(void), so old-style prototypes now get a
compilation error:
/x/libgloss/cris/lcrt0.c:107:1: error: conflicting types for 'start1';\
have 'void(int, char **, char **)'
107 | start1 (int argc, char **argv, char **env)
| ^~~~~~
/x/libgloss/cris/lcrt0.c:105:13: note: previous declaration of 'start1\
' with type 'void(void)'
105 | static void start1 () __asm__ ("__start1") __attribute ((__use\
d__));
Fix by providing a full prototype.
Libgloss is a library for all the details that usually get glossed over.
This library refers to things like startup code, and usually I/O support
for GCC and the C library.
For more details, see the manual under doc/.
