I looked for a "Component" for 'libgcc' but there is no such category so I chose 'inline-asm' as this is an "extra underscore issue" with '.s' files.

Even though I used "-lgcc" there was no 'collision' between the various "conversion functions". The unwanted underscores hide them. I used the soft-fp "C" source files instead of relying on the double underscored versions of these functions that are in libgcc and was able to hand-compile and run ./fp-int-convert-float128.exe . The Testsuite tests for these "conversion functions" could work if they were fixed. These files might have first been discussed here: http://gcc.gnu.org/ml/gcc-patches/2006-05/msg00968.html .
