Subject: 	* coff-pe-read.h (pe_text_section_offset): Declare new
 function. 	* coff-pe-read.c (debug_coff_pe_read): New static variable. 
 (struct read_pe_section_data): Add section_name field. 
 (IMAGE_SCN_CNT_CODE): New macro, if not already defined. 
 (IMAGE_SCN_CNT_INITIALIZED_DATA): Ditto. 
 (IMAGE_SCN_CNT_UNINITIALIZED_DATA): Ditto. 	(get_pe_section_index): New
 function. 	(struct pe_sections_info): New type. 	(get_section_vmas):
 Use new struct pe_sections_info. 	(add_pe_exported_sym): Handle unnamed
 exported function. 	(add_pe_forwarded_sym): New function. 
 (read_pe_truncate_name): Truncate at last dot. 	(pe_as16): New
 function. 	(read_pe_exported_syms): Use ordinal of function to 
 retrieve correct RVA address of function and handle 	forwarded symbol. 
 (pe_text_section_offset): New function. 	(show_debug_coff_pe_read): New
 function. 	(_initialize_coff_pe_read): New function adding 
 'set/show debug coff_pe_read' commands.

	* windows-tdep.c (windows_xfer_shared_library): Use
	pe_text_section_offset function instead of possibly wrong
	0x1000 constant for .text sextion offset.
