djgpp203，保护模式的DOS

JLOC.EXE version 0.6 by John S. Fine <johnfine@erols.com> This program is a linker/locator for use when you need more control over placement of sections within the image, than a standard linker provides. Use this program entirely at your own risk. I make no claim that this program is suitable or safe for any purpose. ZERO-PRICE SHAREWARE: If you continue to use this program after a reasonable initial test, you must register it. You do not need to send any money. Registration consists entirely of sending an EMAIL to johnfine@erols.com to tell me that you are using it, and where you got your copy. Bug reports and suggestions are also welcome, though I can't promise to do anything with them. Documentation: Starting with version 0.3 the documentation is in HTML format in the file JLOC.HTM. Changes: 0.6: * Fixed more bugs in COFF support. 0.5: * Fixed a bug in COFF support that, in version 0.4, caused most self relative relocations from COFF files to be processed incorrectly. * Allowed the start and i_start expressions to be omitted in the control file. JLOC will compute defaults. 0.4: * Support the COFF files (.o) generated by djgpp. I don't know how similar other examples of COFF are to djgpp. They might be supported as well. * Added a patch step at the end of linking. This is useful for link time initialization of descriptor tables and other things that usually require run time initialization. 0.3: * Improved the documentation. * Removed a bug that had caused errors in lower case hex values. * Removed a bug that had caused attempts to write records to the SYM file when no SYM file was open. * Issue a new THEADR record to the SYM file whenever the selector in the next LINNUM record differs from the selector in the previous LINNUM. (This is a work around for a defect in the Microtek ICE, that I use. I don't currently know of any other debugger that uses the SYM file format output by JLOC.)
