+MzScheme and MrEd also compile with Cygwin gcc (a free compiler from
+GNU and Cygnus Solutions), but the result is a Unix-style
+installation, not a Window-style installation. To compile with gcc,
 follow the instructions in plt\src\README (there is a short
 Windows-specific section in that file).
 
+With an MSVC-built MzScheme, compatible extensions can be built with
+other compilers. Build with Cygwin and copy the installed plt\lib\gcc
+to a MSVC-based build to support Cygwin-built extensions. To support
+Borland-built extensions, cd to plt\src\mzscheme\dynsrc and run
+mkbordyn.bat (which requires bcc23.exe, of course).
