Compiling code for IA64 in SuSE SLES 8.1 - using compatible
by Rita Machado 29 Nov '02

Does SuSE SLES 8.1 for IA64 plan to provide compatibility packages for compiling source code with older gcc/g++ compilers (I mean, gcc/g++ 2.96 or 2.95) ? If so, these packages will be available in beta releases ? Thanks, Rita.

I suppose I'll have to take Phillip Thomas' advice, and test for defined'ness of certain values, and #define _{BSD,SVID}_SOURCE accordingly. Thanks.

glibc curiosity

Hi. (if the cross-post is considered harmful, a polite nudge will make me stop :-) I am developing an app under SuSE 7.1 at work, and discovered that in order to get mmap(2) with MAP_ANON, I had to #define __USE_MISC. (I peeked in <bits/types.h>) Asking on #kernelnewbies got me the response 'yeah, MAP_ANON is not POSIX'. Well, ok, but I wonder why glibc was not compiled (on linux) to have this (if that's the right way to phrase it). If anyone can shed light around this, I'd be glad of it (and any other similar things I'm liable to stumble across...) TIA.
