In the gdbsupport configure.ac file, there is an attempt to define TARGET_WORD_SIZE. This is done by running grep on the file ../bfd/bfd-in3.h. The problem with this is, the file bfd-in3.h is generated into the bfd build directory when bfd is configured, and there is no dependency between the gdbsupport module and the bfd module, so, for example, if I do: $ ../src/configure $ make all-gdbsupport Then bfd will neither be configured, or built. In this case TARGET_WORD_SIZE ends up being defined, but with no value because the grep on bfd-in3.h fails. However, it turns out that this doesn't matter; we don't actually use TARGET_WORD_SIZE anywhere. My proposal in this commit is to just remove the definition of TARGET_WORD_SIZE, the alternative would be to add a dependency between configure-gdbsupport and configure-bfd into Makefile.def, but adding a dependency for something we don't need seems pretty pointless.
