redhat-5.2 doesn't have uint32_t


use pthread_sigmask insetad of sigprocmask when possible

reduce heap fragmentation where possible

use strlcpy, strlcmp, etc. when available (on openbsd, maybe others)
	configure script already tests for them

use filedescriptor methods rather than htons/l and friends

QNX doesn't have sys/fcntl.h

printbits for 8,16,32,64 bit-long values

add missing programming docs

get a mingw port working
	(can I use libgw32?)

--------------------------------------------------------------------------------

some systems need -pthread in CFLAGS, other's don't like it

netbsd-3.0 statvfs:
	f_flag
	f_bsize/f_frsize/f_iosize seperately
	f_bresvd
	f_fsidx

file descriptor passing doesn't work on openbsd, cygwin, possibly netbsd

--------------------------------------------------------------------------------

daemonprocess constructor initializes static members, this is lame and messy

document: cygwin needs "file" command to be able to build dll's

freebsd IPV6_V6ONLY??? socket option
sysctl on netbsd?

should be able to associate a zlib handle with a file descriptor and read/write
	compressed data, just like ssl

fix math class

a bunch of static methods can probably be inlined

xml:
	should be able to validate an xml document against the dtd
	test invalid xml
	handle CDATA/internal subsets better
	xml classes need to support entities defined in the DOCTYPE declaration

file class:
	move create*Link/resolveSymbolicLink into link class

implement these classes:
	directorylisting
	link
	pipe
	tty
	pseudotty
	shellcommand
	system
	loginrecord
	messagequeue
	thread
	table (dynamic 2d array)
	generic parser/lexer classes, use them for xmlsax

tests for:
	intervaltimer
	dynamiclib
	math
	rawbuffer
	memorymap
	mutex
	serialportprofile
