86 sym_filepos as well.

153 * nlmcode.h (nlm_object_p): If we can't read the fixed header,

157 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
158 BFD64.
159 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.
160 (BFD64_BACKENDS): Add nlm32-alpha.o. It depends on 64 bit

162 * configure.in (nlm32_alpha_vec): Set target64 to true.
163
164 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are

259 external symbols.
