between your work and theirs. But otherwise, all of these are fair game.
-Rob Landley <rob@landley.net>:
- Add BB_NOMMU to platform.h and migrate __uClinux__ tests to that.
- #if defined __UCLIBC__ && !defined __ARCH_USE_MMU__
+Rob Landley suggested these:
Add a libbb/platform.c
Implement fdprintf() for platforms that haven't got one.
Implement bb_realpath() that can handle NULL on non-glibc.
Cleanup bb_asprintf()
- Migrate calloc() and bb_calloc() occurrences to bb_xzalloc().
Remove obsolete _() wrapper crud for internationalization we don't do.
Figure out where we need utf8 support, and add it.

init
- General cleanup (should use ENABLE_FEATURE_INIT_SYSLOG and ENABLE_FEATURE_INIT_DEBUG).
- Unify base64 handling.
- There's base64 encoding and decoding going on in:
- networking/wget.c:base64enc()
- coreutils/uudecode.c:read_base64()
- coreutils/uuencode.c:tbl_base64[]
- networking/httpd.c:decodeBase64()
- And probably elsewhere. That needs to be unified into libbb functions.

Do a SUSv3 audit
Look at the full Single Unix Specification version 3 (available online at
"http://www.opengroup.org/onlinepubs/009695399/nfindex.html") and
This one's open to everybody, but I'll wind up doing it...
-Bernhard Fischer <rep.nop@anon.at>:
- Makefile stuff:
- make -j is broken, -j1 is forced atm

New debug options:
-Wlarger-than-127
+ Cleanup any big users
Collate BUFSIZ IOBUF_SIZE MY_BUF_SIZE PIPE_PROGRESS_SIZE BUFSIZE PIPESIZE
- Use bb_common_bufsiz1?
+ make bb_common_bufsiz1 configurable, size wise.

diff
Make sure we handle empty files properly:
From the patch man page:
- you can remove a file by sending out a context diff that compares
- the file to be deleted with an empty file dated the Epoch. The
- file will be removed unless patch is conforming to POSIX and the
- -E or --remove-empty-files option is not given.

use bb_perror_msg where appropriate: See
