Compilation Problems

1. Dziwny problem z mount/gcn na heplx43

Zauwazylem ze dziwny problem pojawial mi sie na heplx43 przy kompilacji mount/gcn - generalnie rzeczy CORBOW-ych , ale tylko na heplx43. Bledy byly takie :

Okazuje sie ze skopiowanie do katalogu pliku semaphore.h ( np z /opt/pi/dev/pisys/mount/corba/semaphore.h ) zalatwia sprawe, do konca nie rozumiem o co chodzi
chyba o jakies zle includy , ale to rozwiazuje sprawe i dziala ...
