Here's a new version of the patch.
This one includes some changes to the top-level configury for
libiconv. If you download libiconv, untar it in the src tree, and
rename the directory to "libiconv", it will automatically be built.
gdb will link against the just-built libiconv if the system iconv is
not suitable.
If you do not have libiconv at all, gdb will use a phony iconv that
supports the minimum required for gdb to work.
This version of the patch also has a few bug fixes, relative to the
previous version.
I've built this and run some minimal tests with all the different
configurations. I haven't done full regression tests with all of
them, though.
Let me know what you think. If you have access to non-Linux hosts,
please try this out.

/* How GDB's character set support works

There are commands to set each of these, and mechanisms for
choosing reasonable default values. GDB has a global list of

conversions),
- and so on.
-
- Now, many of these operations are specific to a particular
- host/target character set pair. If GDB supports N character sets,
- there are N^2 possible pairs. This means that, the larger GDB's
- repertoire of character sets gets, the more expensive it gets to add
- new character sets.
-
- To make sure that GDB can do the right thing for every possible
- pairing of host and target character set, while still allowing
- GDB's repertoire to scale, we use a two-tiered approach:
-
- - We maintain a global table of "translations" --- groups of
- functions specific to a particular pair of character sets.
-
- - However, a translation can be incomplete: some functions can be
- omitted. Where there is not a translation to specify exactly
- what function to use, we provide reasonable defaults. The
- default behaviors try to use the "iconv" library functions, which
- support a wide range of character sets. However, even if iconv
- is not available, there are fallbacks to support trivial
- translations: when the host and target character sets are the
- same. */
+ and so on.
+
+ To avoid excessive code duplication and maintenance efforts,
+ GDB simply requires a capable iconv function. Users on platforms
+ without a suitable iconv can use the GNU iconv library. */
