commit r16-5788-ge69bea9b4ccfe79efeec6e87d7d24e6350f31375 Author: Jakub Jelinek <[email protected]> Date: Mon Dec 1 10:44:48 2025 +0100 a68: Fix algol68 build on i686-linux GCC with enabled algol68 fails to build on i686-linux, the error is ../../gcc/algol68/a68-low-multiples.cc:636:31: error: format ‘%ld’ expects argument of type ‘long int’, but argument 2 has type ‘size_t’ {aka ‘unsigned int’} [-Werror=format=] xasprintf is printf family, so it can't use %zd portably, so the following patch uses what is used elsewhere, the HOST_SIZE_T_PRINT* macros with (fmt_size_t) cast - the macros pick the smallest of %d, %ld and %lld depending on SIZE_MAX, but it could still disagree on the exact type and cause warnings or for hosts with say 24-bit size_t it could be even larger, so the cast is needed to handle that. 2025-12-01 Jakub Jelinek <[email protected]> * algol68/a68-low-multiples.cc (copy_multiple_dimension_elems): Use HOST_SIZE_T_PRINT_DEC in xasprintf format string and cast to fmt_size_t.
