PA_FUNC_ATTRIBUTE patch
gcc versions without -Werror=attributes only print a warning to stderr
for unsupported attributes and continue compiling exiting gracefully at
the end if no other errors. So. PA_FUNC_ATTRIBUTE would return success
in such cases.
This solution follows the same method used in AX_GCC_FUNC_ATTRIBUTE from
autoconf-archive by checking a non-empty conftest.err file and returning
failure if there is one.
I don't know if there is any better way of handling this.
