Below [1] is a patch to update boost. It doesn't quite work:

/opt/lmi/third_party/src/boost/libs/filesystem/src/utf8_codecvt_facet.cpp:15:46:
 libs/detail/utf8_codecvt_facet.cpp: No such file or directory

I think the problem is that its "jamfile" requires some component
of "boost::system" from someplace else in their source tree. Of
course, there might be other problems that I don't see yet.

I tried omitting 'utf8_codecvt_facet' from the makefiles, and
using
  CPPFLAGS=-DBOOST_FILESYSTEM_NARROW_ONLY
in the hope that it would make the utf8 thing unnecessary; but,
alas, without success:

/MinGW_/bin/g++  -o test_coding_rules.exe exception.o operations.o path.o 
portability.o alert.o alert_cli.o fenv_lmi.o main_common.o main_common_non_wx.o 
sigfpe.o my_test_coding_rules.o
test_coding_rules.o -L . -L /opt/lmi/local/lib -L /opt/lmi/local/bin 
-lboost_regex-gcc-1_33_1  -lxslt.dll -lxml2.dll         
-Wl,-Map,test_coding_rules.exe.map -Wl,--disable-auto-import
exception.o:C:/MinGW-20050827/bin/../lib/gcc/mingw32/3.4.4/../../../../include/c++/3.4.4/bits/basic_string.h:2041:
 undefined reference to `boost::filesystem::path::native_file_string() const'
...
operations.o: In function `error_code':
/opt/lmi/third_party/include/boost/system/error_code.hpp:309: undefined 
reference to `boost::system::get_system_category()'

And it looks like boost-1.34 has the same dependency and would
have the same issue. Things seem to compile okay; the problem
is all these "undefined reference" errors.

I guess the problem is this lmi design decision:

# Treat certain external libraries as collections of source files to
# be compiled and linked explicitly here, instead of building them
# separately and linking them as normal libraries. Rationale:
#
# boost: the build system provided is not free.
[and it's unique to boost AFAICT]

How would you recommend we attack this problem? If my impression
is correct--that boost's build system isn't free--then we really
ought to find a better way. Do you think it would be hard to
autotoolize boost::filesystem so that we could use it as a shared
library?
