users can immediately benefit from this.
Take a look at the matrix in
- ftp://prep.ai.mit.edu/pub/gnu/ABOUT-NLS
- for the current status (of course better use a mirror of prep).
-
-
-[ 5] Write wordexp() function; this is described in POSIX.2, the
- header <wordexp.h> already exists.
-
- Implementation idea: use some functions from bash.
-
-**** Somebody is working on this. Help may or may not be appreciated.

[ 6] Write `long double' versions of the math functions. This should be
- exp2
- each with float, double, and long double arguments.
+ with long double arguments.
Beside this most of the complex math functions which are new in
ISO C 9X should be improved. Writing some of them in assembler is
[10] Extend regex and/or rx to work with wide characters and complete
implementation of character class and collation class handling.
- It is planed to do a complete rewrite.

[11] Write access function for netmasks, bootparams, and automount
hard and not all services must be supported at once.
-[13] Several more or less small functions have to be written:
-
- + tcgetid() and waitid() from XPG4.2
- + grantpt(), ptsname(), unlockpt() from XPG4.2

[14] We need to write a library for on-the-fly transformation of streams
of text. In fact, this would be a recode-library (you know, GNU recode).
This is needed in several places in the GNU libc and I already have
rather concrete plans but so far no possibility to start this.
+*** The library is available, now it remains to be used in the streams.
+
[15] Cleaning up the header files. Ideally, each header style should
follow the "good examples". Each variable and function should have
int foo __P ((int, int, int, int));
Blargh!
+
+[16] The libio stream file functions should be extended in a way to use
+ mmap to map the file and use it as the buffer to user sees. For
+ read-only streams this should be rather easy and it avoids all read()
+ calls.
+
+ A more sophisticated solution would use mmap also for writing. The
+ standards do not demand that the file on the disk is always in the
+ correct form so it would be possible to enlarge it always according
+ to the page size and install the correct length only for fclose() and
+ fflush() calls.
+
+[17] The sprof program to analyze the profiling data generated by ld.so
+ must be finished. It should have the same functionality as gprof
+ (as far as this is possible).
+
+[18] Based on the sprof program we need tools to analyze the output. The
+ result should be a link map which specifies in which order the .o
+ files are placed in the shared object. This should help to improve
+ code locality and result in a smaller foorprint (in code and data
+ memory) since less pages are only used in small parts.
+
+[19] A user-level STREAMS implementation should be available if the
+ kernel does not provide the support.
+
+[20] More conversion modules for iconv(3). Existing modules should be
+ extended to do things like transliteration if this is wanted.
+ For often used conversion a direct conversion function should be
+ available.
+
+[21] The nscd program and the stubs in the libc should be changed so
+ that each program uses only one socket connect. Take a look at
+ http://www.cygnus.com/~drepper/nscd.html
