LD_PRELOAD is often used to emend the runtime behavior of such libraries. The advantage here is that you don't need to reverse engineer the target library much at all. Just dl_load it under a different name, call it, and fiddle with the return value all you want.

When I read this bit in Mendoza's UNIX to Linux Porting: A Comprehensive Reference, I was surprised that XLC made so much use of the GNU resources.

...the XL C/C++ compilers employ the same GNU libraries, linker, assembler, and binutils as GCC...optimization routines have been developed for and tailored to the POWER architecture. High-performance computing applications, especially those heavily reliant on floating-point operations, often benefit significantly from a simple recompile with XL C/C++.
