At first glance, obj2asm will pretty-print the codeview debug info in 
the object file, and will mix source lines with corresponding assembler 
lines.

Obj2asm also comes with a bunch of other utilities, any one of which is 
worth the $15 if you need them:

◦chmod Change/list file attributes
◦coff2omf Convert COFF object and lib files to OMF
◦diff Compare text files
◦diffdir Compare directory trees
◦dump Dump files
◦dumpexe Dump executable files
◦dumpobj Dump object files
◦flpyimg Read/Write floppy disk image
◦grep Search files for strings
◦libunres Scan libraries for unresolved externals
◦makedep Makefile dependency generator
◦obj2asm Object file disassembler
◦patchobj Patch object files
◦smake Advanced make program
◦whereis Search for files
