The argument of assert_perror should be an errno_t value, not
just a Boolean.

It isn't clear from the commit message that the warning message
occurs at compile time.

Could add an __attribute__ so that GCC can validate that the
arguments of easprintf match the format string, like it already
validates the arguments of asprintf.
