API-space: complete the list of things that constitute public api
Configure
+ fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth
+ libswanted <-> usethreads <-> use64bitint <-> use64bitall <->
+ uselargefiles <-> ...
make configuring+building away from source directory work (VPATH et al)
- _r support
- cross-compilation configuring
+ this is related to: cross-compilation configuring
+ scenarios to consider: the host and the target might have
+ shared filesystems, or they might not (the communication
+ channel might be e.g. rsh/ssh, or some batch submission system)
+ most obviously: they might not share the same CPU
+ meaning: assume nothing about shared properties/resources
+ _r support (see Todo for mode detailed description)
POSIX 1003.1 1996 Edition support--realtime stuff:
POSIX semaphores, message queues, shared memory, realtime clocks,
timers, signals (the metaconfig units mostly already exist for these)
UNIX98 support: reader-writer locks, realtime/asynchronous IO
+ IPv6 support: see RFC2292, RFC2553
Long doubles
figure out where the PV->NV->PV conversion gets it wrong at least
in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
- regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t.
+ regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
+ (?:9|8999\d+) and the like.
+
+64-bit support
+ Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
+ be in some systems the only thing working as quadtype and uquadtype.
Locales
deprecate traditional/legacy locales?
floating point handling: nans, infinities, fp exception masks, etc.
at least the following interfaces exist: fp_classify(), fp_class(),
class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
- fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
- ieeefp.h, fp_class.h. There are metaconfig units for all of these.
+ ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
+ ieeefp.h, fp_class.h. There are metaconfig units for most of these.
+ Search for ifdef __osf__ in pp.c to find a temporary fix that
+ needs to be done right.
fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
both arguments are IVs/UVs
replace pod2html with new PodtoHtml? (requires other modules from CPAN)
turn Cwd into an XS module? (Configure already probes for getcwd())
mmap for speeding up input? (Configure already probes for the mmap family)
sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
- setitimer, getitimer? (the units exist)
+ setitimer, getitimer? (the metaconfig units exist)

keep filenames 8.3 friendly, where feasible
