maj ne se razbrahme nesto ;-) . Zna4i imame installed novite binutils, glibc, 
gcc v neobhodimiq order kvoto si pishe po sites. Imame KDE+QT compiled s 
g++-3.2, applications ot tazi kompilaciq se svyrzvat s C++ libs (ne ot KDE+QT 
upstream sources) koito imash instalirani ot predi i koito sa bili compiled s 
g++  <  g++-3.2, kato naprimer libstdc++. Po tova koeto 4eta (ne sym go test) 
za C++ ABI na g++ 3.2 (pri 3.2 gcc, gobjc i gcj maj nqma promqna, samo g++) 
na gcc.gnu.org i debian-devel, breakage e zadylzhitelen stoto g++-3.2 i 
negovite po-stari versions ste generirat applications/libraries s razli4ni i 
nesyvmestime symbols ...  . Drugoto e predi tova da si prekompiliral i 
libstdc++ (a mozhe bi i oste edna kamara trudno otkrivaemi libraries)  s 
g++-3.2 ... Ot tuk mozhe da se zaformi zdrava bitka s systemata, stoto ako 
prekompilirash libstdc++ s g++-3.2 (da re4em) togava 
my-mom-cool-c++-program-g++2.95.4-compiled nqma da mozhe da link-ne tezi 
.so's. Pokraj tova da re4em ste se nalozhi da prekompilirash i drug lib s 
g++-3.2 i veroqtno po-kysno ste ustanovish 4e 
my-dad-cool-c++-program-g++2.95.4-compiled nqma da ba4ka poradi systata 
pri4ina i t.n.

mda mda, to pishe kak da compile 3.2 , pyk i mozhe da install precompiled 3.2 
(ili 4 - 5 versions da re4em koito sa v Sid ;-) s gcc.wrapper 4e i ccache;-). 
Problema ne e v kompilaciqta/instalaciqta na samoto GCC 3.2 a v 
nesyvmestimoto s older versions C++ ABI, koeto se otrazqva na 
applications/libs compiled s nego i drugi older versions (pri 2.x release 
nemashe takiva promqna) ... vazhnoto e da se izdirqt vsi4ki C++ apps/libs i 
da se compile s g++-3.2 ... (e.g. same apps/libs C++ ABI)

ne. imah predvid ako imam nqkolko versions na GCC (2.X, 3.X vkl. i 3.2) i 
poslednite binuitls , i ako default compiler-a mi e 2.95.4 dali ste ima 
problemi s tezi novi binutils ... stoto tam e i ld i mozhe da stane dosta 
interesno  ... ina4e i az za feedback se oslushvam, ma gledam otstrani ... 4e 
case-a e dosta interesen ... ;-)
