No offense taken, and no apology necessary. Sorry if my reply sounded a
bit sarcastic, I didn't mean it that way.

: It's a gcc-ism. This is something caused by the -fpic or (I think)
: the -fPIC options. From the GCC info file:
:
: `-fpic' Generate position-independent code (PIC) suitable for use in a
: shared library, if supported for the target machine. Such code
: accesses all constant addresses through a global offset table
: (GOT). The dynamic loader resolves the GOT entries when the
: program starts (the dynamic loader is not part of GNU CC; it is
: part of the operating system). If the GOT size for the linked
: executable exceeds a machine-specific maximum size, you get an
: error message from the linker indicating that `-fpic' does not
: work; in that case, recompile with `-fPIC' instead. (These
: maximums are 16k on the m88k, 8k on the Sparc, and 32k on the
: m68k and RS/6000. The 386 has no such limit.)
:
: Position-independent code requires special support, and therefore
: works only on certain machines. For the 386, GNU CC supports PIC
: for System V but not for the Sun 386i. Code generated for the
: IBM RS/6000 is always position-independent.
:
: `-fPIC'
: If supported for the target machine, emit position-independent
: code, suitable for dynamic linking and avoiding any limit on the
: size of the global offset table. This option makes a difference
: on the m68k, m88k, and the Sparc.

: Position-independent code requires special support, and therefore

Okay, I'll give the pic/PIC compile options a try. Thanks
