Most my porting to borland recently has involved a couple of new bugs
introduced in BCB6. Rather than testing compiler and version
everywhere, should I instead create some BOOST_SOME_DEFECT macros in the
borland config file and test for those instead? If so, any suggestions
for the macro names would be appreciated.
The two defects are:
The various std::isdigit, islower, isalnum etc. convenience functions
will not compile.
The fix in this case is to simply implement the function directly via
std::use_facet<std::ctype<Ch> >( oss_.rdbuf()->getloc() ).is(
std::ctype_base::digit, c )
[Also note in the general case it may be necessary to remove_const on
the character type]
Second problem is with the STLport implementation of the STL. This
places all std names into the namespace _STL and uses macro-magic to
make this look like std. Unfortunately, for reason I have not fully
determined, that magic sometimes comes up short.
Often the fix is to add a using directive:
swap( a, b );
Sometimes the fix is to explicitly specify namespace _STL instead.
_STL::swap( a, b );
There are cases where either fix works, and specific cases where only
one form or the other works.
As best I can figure, these macros should be defined
#if defined(__BORLAND__) \
&& __BORLANDC__ >= 0x0560 \
&& __BORLANDC__ <= 0x0561
In the latter case we should test that the STLport library has been
chosen as well.
Are either of these cases already covered by another existing
Do either of these problems look familiar to users of other compilers?
[Note: I have not tested with the Kylix compiler but suspect it will
have similar issues]
