dnl Please note, that on HPUX two different stages of module compilation occurs, since
dnl while compiling modules, the compiler does not allow you to give arguments
dnl to the linker. (I did not design this)
dnl So we need -c in the first stage of module compilation.
dnl In the second stage, we link the modules via ld -b.
dnl Additionally, HPUX does not like -export-dynamic, it likes -E instead.
