Hi Duncan, > I am in the process of verifying that the GNU linker (gcc 3.3.2 VxWorks AE653) The GNU linker is not part of the GCC project. It is part of the Binutils project, so this question really should be asked on the binutils mailing list: binutils@sourceware.org > However, does ld include a decompression feature, No it does not.
