I also have the exact the problem when upgrading to boost 1.49.0

[Antony Polukhin]

(In [77691]) Fixes #6670 (now using BOOST_NO_UNICODE_LITERALS macro)

[Antony Polukhin]

(In [77721]) More workarounds for fixed #6670 (disable basic char16_t and char32_t tests for some compilers, disable optimizations for them)

(In [77745]) More workarounds for fixed #6670 (disable more char16_t and char32_t tests for some compilers)

[Antony Polukhin]

(In [77804]) Merge lexical_cast from trunk:

• fixed #6717 (now lexical_cast won`t try to support non confirming swprintf)
• fixed #6670 (now using BOOST_NO_UNICODE_LITERALS macro to detect unicode literals support)
• rewritten Jamfile
