Hi Robert,

I come back to you with following comments regarding this small bug report
I transmited a time ago to gnu.org.

PS: I continued a bit to try to compile Opencascade onto linux for parisc.
I had to stop because:
1) ld or gcc bug 
2) not enough place on 9Gb disk (but I notice that I could avoid to build
static libs, that will certainly help me as soon as I could recover some
place)

See you,
    Joel
