[boost] boost::config BOOST_BUGGY_SYSTEM would be nice

Hi !  If you didn't knew already, under windows, I didn't tested all
compiler, but vc++ 6.0 have this issue, well system(const char*) is buggy:
you have to double-quote the command to execute.

Example
instead of
string callstring = " \"c:\\Program File\\a program\\a executable.exe\"
\"--a argument\"";
system(callstring.c_str() );
( cout << callstring     would produce : "c:\Program File\a program\a
executable.exe" "--a argument" )

you have to do
string callstring(" \"\"c:\\Program File\\a program\\a executable.exe\"
\"--a argument\""\");
system(callstring.c_str() );
(cout << callstring    would produce :  " "c:\Program File\a program\a
executable.exe" "--a argument"  ")

i.e. you have to produce:
" "a file containing whitespace" "-a argument"  "

I didn't tested this issue under all os, since microsoft are the only one
who had the idea to put whitespace in filename

therefore, it would be nice to have a macro BOOST_BUGGY_SYSTEM to know if we
have to double-quote the system(  ) calls

for now it would be only
#ifdef WIN32
#define BOOST_BUGGY_SYSTEM
#endif

but additionnal testing would be required

thanks for your time
