Thanks for the help. The following works for me:

  set BOOST_FILESYSTEM_LIB=D:\C++\Boost\Current\libs\filesystem\build\bin\libboost_filesystem.lib
  g++ -Id:\C++\Boost\Current -o simple_ls.exe simple_ls.cpp %BOOST_FILESYSTEM_LIB%

Unfortunately, I haven't been able to find a way to make it work for VC7.1.
This is my most recent effort:

  set BOOST_FILESYSTEM_LIB=D:\C++\Boost\Current\libs\filesystem\build\bin\libboost_filesystem.lib
  cl /TP /W4 /WL /GX /GR -ID:\C++\Boost\Current simple_ls.cpp /link /defaultlib:%

This elicits multiply-defined symbols errors:

  Microsoft (R) Incremental Linker Version 7.10.3077

I expect that I can figure out the LNK4098 warning myself, but I'm not sure
what to do about the LNK2005s. For that matter, I'm not sure if I've
formed the command line correctly for what I want to do. My attempts to
decipher the documentation for the command line compiler and linker and
interactions thereof have been in vain. Does anybody happen to know what
the right invocation is? If not, that's fine, I can post elsewhere, as
this is really an MSVC question, not a Boost question.
