+/*
+ This program allows you to build the files necessary to create
+ DLLs to run on a system which understands PE format image files.
+ (eg, Windows NT)
+
+ A DLL contains an export table which contains the information
+ which the runtime loader needs to tie up references from a
+ referencing program.
+
+ The export table is generated by this program by reading
+ in a .DEF file or scanning the .a and .o files which will be in the
+ DLL. A .o file can contain information in special ".drective" sections
+ with export information.
+
+ A DEF file contains any number of the following commands:
+
+
+ NAME <name> [ , <base> ]
+ The result is going to be <name>.EXE
+
+ LIBRARY <name> [ , <base> ]
+ The result is going to be <name>.DLL
+
+ EXPORTS ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] ) *
+ Declares name1 as an exported symbol from the
+ DLL, with optional ordinal number <integer>
+
+ IMPORTS ( [ <name> = ] <name> . <name> ) *
+ Ignored for compatibility
+
+ DESCRIPTION <string>
+ Puts <string> into output .exp file in the .rdata section
+
+ [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
+ Generates --stack|--heap <number-reserve>,<number-commit>
+ in the output .drective section. The linker will
+ see this and act upon it.
+
+ [CODE|DATA] <attr>+
+ SECTIONS ( <sectionname> <attr>+ )*
+ <attr> = READ | WRITE | EXECUTE | SHARED
+ Generates --attr <sectionname> <attr> in the output
+ .drective section. The linker will see this and act
+ upon it.
+
+
+ A -export:<name> in a .drective section in an input .o or .a
+ file to this program is equivalent to a EXPORTS <name>
+ in a .DEF file.
+
+
+
+ The program generates output files with the prefix supplied
+ on the command line, or in the def file, or taken from the first
+ supplied argument.
+
+ The output files are <prefix>.exp.s and <prefix>.lib.s
+
+ The .exp.s file contains the information necessary to export
+ the routines in the DLL. The .lib.s file contains the information
+ necessary to use the DLL's routines from a referencing program.
+
+
+
+Example:
+
+file1.c:
+ asm (".section .drectve");
+ asm (".ascii \"-export:adef\"");
+
+ adef(char *s)
+ {
+ printf("hello from the dll %s\n",s);
+ }
+
+ bdef(char *s)
+ {
+ printf("hello from the dll and the other entry point %s\n",s);
+ }
+
+file2.c:
+ asm (".section .drectve");
+ asm (".ascii \"-export:cdef\"");
+ asm (".ascii \"-export:ddef\"");
+ cdef(char *s)
+ {
+ printf("hello from the dll %s\n",s);
+ }
+
+ ddef(char *s)
+ {
+ printf("hello from the dll and the other entry point %s\n",s);
+ }
+
+ printf()
