I don't have any MS compilers, that's why I ask. And I personally doubt it, esp. considering how lame even WinME codepage support was. (Thanks to people like Henrique and Eduardo, FreeDOS has very good codepage + country coverage.) C89 seemed to require 15 headers, and locale.h was one, but almost all DOS compilers I have don't include it (or even for the handful that did, a wimpy test didn't indicate it to actually work). Which sucks. I'm on a different computer right now, but I'm pretty sure only three compilers had locale.h (if I'm remembering correctly). There may be more, but I haven't got access to (nor ever used) them nowadays. CC386 apparently has some rough support for "en_EN", "en_GB", "fr_FR", and that's all I think (though I don't know how to activate it properly). I'm not sure what that entails. OpenWatcom has locale.h, but its headers are just confusing (thanks to supporting a billion OSes), so I have no idea if it's just empty stubs for DOS (probably) vs. works fine on Windows. (To most people, supporting cp850 was exotic enough, I guess.) They did used to have Japanese error messages for the compiler proper, but that's not the same as setlocale() and lconv->currency_symbol, etc. (Though their included vi clone was made 8-bit clean in latest release, I think, but I haven't tested.) DJGPP (GCC) you'd think would be the best. But I'm 99% sure they never bothered with multi-byte. At least, last I heard they only officially supported the default "C" locale. I know there were some third-party efforts. A quick check shows that Mark E. (Elbrecht?) did some incomplete wchar.h work (stubs only??) that was probably never patched in. Also "Jack" (Daisuke Aoyama) did some rough port of Bash 1.14.7 back in 1997 that supported Shift-JIS via two add-on libs. Also, CWS at one time wanted to support iconv.dxe, but I guess they never finished that (nor even 2.04 beyond "beta" status). There is a lloc*.zip file (only) in /current/v2tk/ or such, "liblocale" I think, and that (IIRC) basically patches some internal stuff to support COUNTRY.SYS, but I've never tested it very well. Long story short: I'm just curious. I would honestly be surprised if *nobody* supported it. Yeah, I have to admit, I don't need it. Heck, my alt-lang (E-o) doesn't even have a country (or support, obviously, heh) though it has a codepage. ;-) I hate to admit, but it's probably due to U.S. apathy since everything here is English only. Which sucks. But since we've discussed i18n on FreeDOS several times over the past few months, I figured I'd mention it (locale.h) in case anybody knew offhand. I know various FD tools support COUNTRY.SYS and codepages, but I was more curious if any DOS C compiler (since C is "everywhere") did, esp. re: ANSI C89, which mandated it. ------------------------------------------------------------------------------ Special Offer -- Download ArcSight Logger for FREE!
