That looks great. Can that be generalized? There must be other
modules inside Cygwin that also need to initialize constant structures.
Could all of these initializers be called from some central place, if needed,
rather than having everybody maintain a separate "isinitialized" variable and
add lines in the middle of dll_crt0_1 ()?
In fact we may not even need a central "isinitialized" variable if the
centralized routine is skipped only in case of forks.
