Compiling 'compat/obstack.c' with Clang on Linux and macOS fails with
different errors:
On Linux:
CC compat/obstack.o
compat/obstack.c:330:31: error: incompatible pointer types initializing
'void (*)(void) __attribute__((noreturn))' with an expression of type
'void (void)' [-Werror,-Wincompatible-pointer-types]
__attribute_noreturn__ void (*obstack_alloc_failed_handler) (void)
^
Remove '__attribute_noreturn__' from the function's declaration and
definition to resolve this build error.
On macOS:
compat/obstack.h:223:3: error: expected function body after function declarator
__attribute_pure__;
^
compat/obstack.h:151:29: note: expanded from macro '__attribute_pure__'
# define __attribute_pure__ _GL_ATTRIBUTE_PURE
Remove '__attribute_pure__' to resolve this build error.
With this patch it's now possible to compile 'compat/obstack.c' both
with GCC and Clang on both on Linux and macOS.
