*eeww* There really was a group movement toward environment variables?
Could you perhaps point me to this thread?

(Env vars are bad, IMHO. It's not fun to debug an application for hours
only to find out that the unexplained behavior was caused by some
obscure/undocumented env var)

p.s. why would "!!" fix bugs on some platforms if ap_exists_config_define
can only return 0 or 1? I can only see using !! to normalize some non-bool
return to 0/1 for some weird logic, and even then it's not readable.
