15 /* iconv arg2 type: libiconv in Ports uses "const char* * inbuf" and was
16 * traditionally the only approach available. The iconv functionality
17 * in libc is "char ** restrict src".
19 * <https://www.freebsd.org/doc/en/books/porters-handbook/using-iconv.html>
20 * says that libc has iconv since 2013, in 10-CURRENT. FreeBSD man-pages
21 * shows it included in 10.0-RELEASE. Writing this in 2017, 10.3 is the
22 * oldest supported release, so we should assume non-libiconv by default.
23 * (Actually, people still using old releases past EOL; we shouldn't support
24 * them but I don't want to deal with howls of complaints because we dare
25 * to not support the unsupported, so guard this on FreeBSD 10+)
27 * Thus we no longer override iconv.
29 * However, if libiconv is installed, and anything adds /usr/local/include
30 * to include-path (likely) then we'll get that. So define a variable
31 * which makes the libiconv try to not interfere with OS iconv.
