27/* iconv arg2 type: libiconv in Ports uses "const char* * inbuf" and was
28 * traditionally the only approach available. The iconv functionality
29 * in libc is "char ** restrict src".
30 *
31 * <https://www.freebsd.org/doc/en/books/porters-handbook/using-iconv.html>
32 * says that libc has iconv since 2013, in 10-CURRENT. FreeBSD man-pages
33 * shows it included in 10.0-RELEASE. Writing this in 2017, 10.3 is the
34 * oldest supported release, so we should assume non-libiconv by default.

35 * (Actually, people still using old releases past EOL; we shouldn't support
36 * them but I don't want to deal with howls of complaints because we dare
37 * to not support the unsupported, so guard this on FreeBSD 10+)

38 *
39 * Thus we no longer override iconv.
40 *
41 * However, if libiconv is installed, and anything adds /usr/local/include
42 * to include-path (likely) then we'll get that. So define a variable
43 * which makes the libiconv try to not interfere with OS iconv.
