make configuring+building away from source directory work (VPATH et al)
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
+ host vs target: compile in the host, get the executable to the target,
+ get the possible input files to the target, execute in the target,
+ get possible output files back to to host. this needs to work
+ both during Configure and during the build. You cannot assume
+ shared filesystems between the host and the target, executing
+ the target executable may involve e.g. rsh
_r support (see Todo for mode detailed description)
POSIX 1003.1 1996 Edition support--realtime stuff:
POSIX semaphores, message queues, shared memory, realtime clocks,
Regexen
make RE engine thread-safe
+ a way to do full character set arithmetics: now one can do
+ addition, negate a whole class, and negate certain subclasses
+ (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
+ intersect characters/classes, like described in the Unicode technical
+ report on Regular Expression Guidelines,
+ http://www.unicode.org/unicode/reports/tr18/
+ (amusingly, the TR notes that difference and intersection
+ can be done using "Perl-style look-ahead")
+ difference syntax? maybe [[:alpha:][^abc]] meaning
+ "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
+ (maybe bad, as we explicitly disallow such 'ranges')
+ intersection syntax? maybe [[..]&[...]]?
POSIX [=bar=] and [.zap.] would nice too but there's no API for them
=bar= could be done with Unicode, though, see the Unicode TR #15 about
normalization forms:
