'Twould be nice to have them all uniformly listed.) Secondly, I was under the impression that 802.11g could support up to 54Mbps.

Hy, I'am trying to compile a little project with Borland C++ 5 on my redhat 7.0 box with the rpm package from linux-easy for wine. The IDE is working correctly, compilation goes ok but when comes time to link all object files together Borland c++ stop to work. I tried to export project file and do a make, it is the same problem ilink32.exe seems to hang.... Thanks for help Jean-Francois

...ile which is memory-mapped. Apparently, on 32bits distros, and on most 64bits distros, only a part of the locale-archive file is mmapped: for instance on CentOS 32 bits: $ pmap $$ b7689000 2048K r---- /usr/lib/locale/locale-archive Only 2MB of the file are mmapped, while the file is actually ~54MB. Some distros only install a small subsets of languages, for instance on my Ubuntu 12.04, this file is only ~3MB. I still don't get the reason, but CentOS x86_64 6.2 (and 6.3) mmappes the *entire* file: $ pmap $$ 00007f217fae4000 96836K r---- /usr/lib/locale/locale-archive Consequence: ev...
