These files are some GNU utilities for operating on binary files. GNU make, which used to be included here, is now distributed in a separate tar file. Report bugs in these programs to bug-gnu-utils@prep.ai.mit.edu. Please note in the bug report which version of the binutils you are using. Prior to version 1.7, the versions were identified by the top line of the ChangeLog. Define USG with `-DUSG' when compiling these programs to run on system V. COFF is not supported, but we do support a way of encapsulating GNU executable files with COFF headers. Use -DCOFF_ENCAPSULATE when you compile, to enable this feature. In order to use encapsulation, you must use entirely GNU tools, including these plus GAS, GCC and GDB. You will need to convert the system libraries to BSD object file format. Use the shell script libconvert (which uses robotussin) for that. The GNU version of ld has some interesting features: 1. Undefined and multiply-defined global symbol errors are now associated with specific source files and line numbers, and printed in a format M-x next-error can parse. 2. Normally no output is written if there are serious errors. Use the option `-noinhibit-exec' if you want an output file anyway. 3. Global symbols can be defined by indirection to other symbols. See comments at definition of N_INDR in ld.c 4. LD can accumulate sets of related values from all the object files that are being linked together, and put them into a vector that can be accessed at run time. Thus, you can arrange for each file to have initializations to be run when your `main' function sees fit, without having to know the names of all the files that are linked together. See comments at definition of N_SETA, etc., in ld.c.
