 generates both EXE and DLL files. DLL symbols can be imported thru DEF files
 generated with the @code{tiny_impdef} tool.
 
-Currently TCC for Windows cannot generate nor read PE object files, so ELF
-object files are used for that purpose. It can be a problem if
-interoperability with MSVC is needed. Moreover, no leading underscore is
-currently generated in the ELF symbols.
+On the object file level, currently TCC supports only the ELF format, not COFF 
+as used by MINGW and MSVC. It is not possible to exchange object files or 
+libraries between TCC and these compilers.  However libraries for TCC from objects 
+by TCC can be made using the @code{tiny_libmaker} tool or MINGW's @code{ar}.

+No leading underscore is generated in the ELF symbols.  Only functions (no
