dan asked to keep everyone up to date on any issues i've had while
developing mod_parrot.  following are the problems i've encountered.

---

i currently get parrot's configuration from config_lib.pasm.  however, it
is not readily apparent from the configuration the libraries and flags
required to link with libparrot.a.  in particular:

* if linking with ICU, which ICU should we use, and which libraries
  and linker flags are required?

* if parrot is linked with libstdc++ behind the scenes (ICU?), it is not
  listed in the configuration, so i have to add -lstdc++ manually.  i may
  just have to get this from ICU's configuration, but i think parrot, like
  perl 5 right now, should be able to list all its required dependencies
  in one place to make life easier for embedders.

---

many of the functions i need to perform in an embedding environment (PMC
value manipulation, calling parrot subroutines, etc.) are only available
if i include extend.h in addition to embed.h.  if these headers are to be
mutually exclusive (i believe they were meant to be), then all the
functionality i just mentioned should be availble to both embedders and
extenders in another "environment neutral" header.

---

there is no NCI signature for (char **), which i need this for calling
ap_get_basic_auth_pw(request_rec *r, char **).  'B', which is (void **)
doesn't seem to work for this situation.  the function returns the pointer
to the password in a buffer allocated by apache, and that would have to be
converted to a parrot string.  as for the buffer, in mod_parrot's case
memory leaks won't really be a problem here due to apache's memory pools,
but i'd say apache is the exception, not the rule.

right now i have a small C wrapper that calls ap_get_basic_auth_pw and
returns the "parrot stringified" password in a register, but it's not as
clean as it should be.  i'm not sure if this is something that can be
fixed for all applications of char **, but it doesn't hurt to ask.  :)

---

that's it -- really no *major* problems to report, and that says a lot
about the state of parrot right now.
