Hmm,

why does this work for me on openSUSE then?

The line:
gcc -c -I. -I. -I../include -I../include    -Wall -pipe -fno-strict-aliasing -Wdeclaration-after-statement -Wwrite-strings -W
type-limits -Wpointer-arith  -march=i586 -mtune=i686 -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funw
ind-tables -fasynchronous-unwind-tables -g  -o preloader.o preloader.c

works fine here. Are you passing in -fPIC?

Ciao, marcus
