Remove the `unsigned' from some `unsigned char*' parameter types.
Add casts via UCHAR where necessary to avoid problems with unwanted
sign extension. Based on a patch from Kaveh Ghazi to appease Irix4's
cc compiler.

Move function-spanning `#if ...BSIZE' stmt to follow inclusion of
sys/param.h since BSIZE is sometimes defined in sys/param.h.
Based on a patch from Philippe De Muyter.
Remove definitions of those symbols.
* src/csplit.c: Move inclusion of regex.h/rx.h to follow system.h
since it now includes limit.h which defines RE_DUP_MAX.
* src/nl.c: Likewise.
* src/tac.c: Likewise.
