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. | |
