support gcc 1.42: it only can __attribute__((aligned (1))) but no others, 

it can’t do -Werror, that’s why it mis-detects attribute support.
ignore the warnings (unused variables, uninitialised values, control flow)
as I checked them and they are not valid. gcc 1.42 (BSDi modified) compiles
a very fine mksh
