It's unclear to me why that happens; the compiler might see the stuff
expanded from ATTRIBUTE_PRINTF_1 as "old-style parameter declarations",
but at least in Debian 12 the relevant macro definitions are:
ansidecl.h
126:#ifndef ATTRIBUTE_NONNULL
128:# define ATTRIBUTE_NONNULL(m) __attribute__ ((__nonnull__ (m)))
130:# define ATTRIBUTE_NONNULL(m)
132:#endif /* ATTRIBUTE_NONNULL */
157:#define ATTRIBUTE_PRINTF(m, n) __attribute__ ((__format__ (__printf__, m,
n))) ATTRIBUTE_NONNULL(m)
158:#define ATTRIBUTE_PRINTF_1 ATTRIBUTE_PRINTF(1, 2)
and I don't see that this produces an old-style parameter declaration.

On my system the line before is:
hash_128 gflibcc_hash_disasm2 = {
0x32,0x5C,0x60,0x83,0x70,0xE4,0x64,0x50,0x2C,0xE5,0xD2,0xCC,0x90,0x2C,0x1F,0x41
};
I don't know why the C compiler would expect a "{" after that.
