[bug-gnu-libiconv] inconsistency in EILSEQ definition...

[Joel Brobecker]

Hello,

A few weeks ago, I reported a problem to gnulib where the errno
module would still be missing the EILSEQ macro on systems that
do not define it (in this particular case: LynxOS 178):
http://lists.gnu.org/archive/html/bug-gnulib/2012-10/msg00088.html

The problem was solved by defining EILSEQ to an arbitrary value (2015).
See commit daf7f8c02242c535d596231e2f655109b97fa2bc.

However, when I suggested the use of the errno module in GDB,
one of the maintainers remarked that libiconv uses a different
strategy, which is to define it to ENOENT.
http://www.sourceware.org/ml/gdb-patches/2012-12/msg00554.html

This makes the two libraries incompatible at this level.

In terms of the build error on Lynx178, what I ended up doing
was compile with -DEILSEQ=ENOENT.

In the future, I am wondering whether it might be helpful for
GNU projects to synchronize their approach to this issue.
