18 | /* iconv arg2 type: libiconv in Ports uses "const char* * inbuf" and was |
| 19 | * traditionally the only approach available. The iconv functionality | |
| 20 | * in libc is "char ** restrict src". | |
| 21 | * | |
| 22 | * <https://www.freebsd.org/doc/en/books/porters-handbook/using-iconv.html> | |
| 23 | * says that libc has iconv since 2013, in 10-CURRENT. FreeBSD man-pages | |
| 24 | * shows it included in 10.0-RELEASE. Writing this in 2017, 10.3 is the | |
| 25 | * oldest supported release, so we should assume non-libiconv by default. | |
| 852e25c5 PP |
26 | * (Actually, people still using old releases past EOL; we shouldn't support |
| 27 | * them but I don't want to deal with howls of complaints because we dare | |
| 28 | * to not support the unsupported, so guard this on FreeBSD 10+) | |
| 863bd541 PP |
29 | * |
| 30 | * Thus we no longer override iconv. | |
| 31 | * | |
| 32 | * However, if libiconv is installed, and anything adds /usr/local/include | |
| 33 | * to include-path (likely) then we'll get that. So define a variable | |
| 34 | * which makes the libiconv try to not interfere with OS iconv. | |
