* stabsread.h (struct stab_section_list): Define.

Browse Source 
(coffstab_build_psymtabs): Remove staboff and stabsize parameters.
	Add textaddr, textsize, and stabs parameters.
	* gdb-stabs.h (struct dbx_symfile_info): Remove text_sect field.
	Add text_addr and text_size fields.
	(DBX_TEXT_SECT): Don't define.
	(DBX_TEXT_ADDR, DBX_TEXT_SIZE): Define.
	* coffread.c: Include <ctype.h>.
	(struct coff_symfile_info): Remove stabsect and stabindexsect
	fields.  Add textaddr, textsize, and stabsects fields.
	(coff_locate_sections): Record the address of the .text section,
	and total the sizes of all sections with names beginning with
	".text".  Don't bother to record a .stab.index section (COFF
	doesn't use them).  Make a linked list of all sections with names
	beginning with ".stab".
	(coff_symfile_read): Adjust call to coffstab_build_psymtabs for
	new parameters.
	* dbxread.c (dbx_symfile_read): Use DBX_TEXT_ADDR and
	DBX_TEXT_SIZE, rather than getting both from DBX_TEXT_SECT.
	(dbx_symfile_init): Set DBX_TEXT_ADDR and DBX_TEXT_SIZE, not
	DBX_TEXT_SECT.
	(elfstab_build_psymtabs): Likewise.
	(stabsect_build_psymtabs): Likewise.
	(symbuf_sections, symbuf_left, symbuf_read): New static variables.
	(fill_symbuf): If symbuf_sections is not NULL, read symbols from
	multiple sections.
	(coffstab_build_psymtabs): Remove staboffset and stabsize
	parameters.  Add textaddr, textsize, and stabsects parameters.
	Set DBX_TEXT_ADDR and DBX_TEXT_SIZE, not DBX_TEXT_SECT.  Handle
	multiple stabs sections.
	* os9kread.c (os9k_symfile_read):  Use DBX_TEXT_ADDR and
	DBX_TEXT_SIZE, rather than getting both from DBX_TEXT_SECT.
	(os9k_symfile_init): Set DBX_TEXT_ADDR and DBX_TEXT_SIZE, not
	DBX_TEXT_SECT.
