* configure.in: When testing for a free() declaration in system header files,
cast the address to a function pointer, not to an integer.

* write.c (fix_new_internal): Call TC_INIT_FIX_DATA if TC_FIX_TYPE is defined.
Don't initialize fx_bsr.  Verify that fx_size field is wide enough to hold
stored value.
* write.h (struct fix): Change tc_fix_data to type TC_FIX_TYPE if that is
defined, otherwise omit it.  Delete fx_bsr.  Change fx_size to unsigned char.
* config/tc-i960.h (TC_FIX_TYPE, fx_bsr, TC_INIT_FIX_DATA): New macros.
* config/tc-ns32k.h (TC_FIX_TYPE, fx_bsr, TC_INIT_FIX_DATA): New macros.
* config/tc-hppa.h (TC_FIX_TYPE): Define as PTR.

* config/tc-i860.c (md_apply_fix): Delete code for checking fx_im_disp, and for
handling non-zero values, since it never gets set after being initialized to
zero.

* write.h (struct fix): Make fx_im_disp always 2 bits, since the only tc-*
files actually using it need that much.

NS32K changes from Ian Dall:
* configure.in: Treat ns32k-pc532-ux* like ns32k-pc532-mach*, and
ns32k-pc532-lites* like ns32k-pc532-netbsd*.
* config/tc-ns32k.h (LOCAL_LABELS_FB): Define to 1.
