Trivial patch to fix compilation with Sun CC in alt stringstream

[Vadim Zeitlin <vz-boost@…>]

The following trivial patch fixes compilation of boost/format/alt_sstream_impl.hpp with Sun CC:

boost/format/alt_sstream_impl.hpp

@@ -249 +249 @@
                     add_size /= 2;
                 if(0 < add_size) {
                     new_size += add_size;
-                    newptr = alloc_.allocate(new_size, is_allocated_? oldptr : 0);
+                    newptr = static_cast<Ch *>(alloc_.allocate(new_size, is_allocated_? oldptr : 0));
                 }
 
                 if(0 < prev_size)

I don't know why (as I don't know this code at all...) but allocate() returns void * and not char * in this STL implementation so it fails to compile without an explicit cast.

Maybe there is a better way to deal with this but I hope that if no other solution is found, this patch could be applied to allow to use Boost with Sun CC with its (old and broken...) standard library.

TIA!

Boost only supports the stlport standard library with Sun CC. The default standard library is quite broken in many other ways as well.

[Vadim Zeitlin <vz-boost@…>]

Well, yes, it's broken but if you can't avoid using it (because customers code links with it and not STLport (which, BTW, is broken in its own, different, ways)) this trivial change still allows you to compile the code and our code that uses this header does work (well, as far as unit tests show, anyhow). So while, as mentioned in #3893, I don't plan to work around all bugs in Sun^H^H^HOracle STL it would still be nice if some simple ones to work around could be fixed.

Fixed in [62825].
