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*).
