- Subject: declare canonicalize_file_name
GDB uses canonicalize_file_name if it detects it in libc,
but doesn't define _GNU_SOURCE to get it declared. This
results in the compiler thinking that the function returns
an integer, which results in the pointer value being
truncated on ia64.
I figured providing a declaration was safer than forcing
_GNU_SOURCE.
Ok?
r~
* configure.in (canonicalize_file_name): Look for declaration.
* configure, config.in: Rebuild.
* utils.c (canonicalize_file_name): Provide decl if required.
