* __bb_exit_func.c: New file, from David Mosberger-Tang.

Browse Source 
Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <davidm@piston.cs.arizona.edu>

* All *.c: More cleanup towards GNU format.

* gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record): replaced sizeof
(bfd_vma) by size (char*) because Ken tells me that bfd_vma is only guaranteed
to be at least as big as a pointer.

(GMON_Record_tag): added explicit enumeration values to ensure compatibility
across compilers.

* gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by sizeof(char*).
