TODO list for the uClibc 0.9.27 release:
-------------------------------------------------
- *) Implement some mechanism (perhaps encoded in the .so name,
- perhaps using an abi tag magically embedded into each object)
- for flagging config options that break the ABI. Options
- such as UCLIBC_HAS_SOFT_FLOAT, UCLIBC_HAS_THREADS, UCLIBC_HAS_LOCALE,
- and perhaps others (finalize list) produce a lib with a differing
- ABI. Make it so apps cannot use an ABI mis-matched uClibc.
*) Fix syscall() on mips
- *) Finish up current ldso cleanups
- *) Fix dlopen, for both static and dynamic cases, and make it
- actually comply with SuSv3
*) Fix use of __secure in __uClibc_init() for so that we prevent
starting staticly linked SUID binaries where the standard file
descriptors are not opened. For dynamically linked binaries,
ldso does this for us.
+ *) Audit header files. Remove prototypes for all functions that
+ are not supported -- especially needed for the libm headers.
+ *) Audit header files. When options are disabled, also disable
+ them in the include files as well by checking for the proper
+ define from include/bits/uClibc_config.h (pulled in from features.h)

not be built with --enable-sjlj-exceptions for C++ exception handling
to work.
*) Implement the float and long double versions of math funcs
using wrappers on top of the double versions (size / precision
trade off where size clearly wins).
