Re: ‘iconv’ fails to build on NetBSD 5.1

Hi Bruno,

So it’s only ‘iconv_open-utf’, but it should drag the other iconv*
modules AIUI.

# iconv.m4 serial 11 (gettext-0.18.1)

This is older than the one in the Gnulib repo I used.

(Time passes...)

The bug originates in Nixpkgs/NixOS, which has a wrapper around
‘aclocal’ to make it honor $ACLOCAL_PATH (this is necessary with Nix
since each package is installed in its own path.)  The problem is that
the wrapper would *prepend* the -I flags corresponding to $ACLOCAL_PATH
instead of appending them, hence the bug.

Sorry for the noise!

Thanks,
Ludo’.
