 Hello,

 1.45.0 is the seventh version of boost, which I am successfully using with
 a Texas Instruments compiler (actually, only some header-only parts of
 boost).

 However, for every new version of boost i must make this change in boost:
 {{{
 Index: integer.hpp
 ===================================================================
 --- integer.hpp (revision 41)
 +++ integer.hpp (working copy)
 @@ -89,7 +89,8 @@
    template <> struct exact_signed_base_helper<sizeof(int)* CHAR_BIT> {
 typedef int exact; };
    template <> struct exact_unsigned_base_helper<sizeof(unsigned int)*
 CHAR_BIT> { typedef unsigned int exact; };
  #endif
 -#if ULONG_MAX != UINT_MAX
 +#if ULONG_MAX != UINT_MAX && ( !defined __TI_COMPILER_VERSION__ || \
 +               ( __TI_COMPILER_VERSION__ >= 7000000 && !defined
 __TI_40BIT_LONG__ ) )
    template <> struct exact_signed_base_helper<sizeof(long)* CHAR_BIT> {
 typedef long exact; };
    template <> struct exact_unsigned_base_helper<sizeof(unsigned long)*
 CHAR_BIT> { typedef unsigned long exact; };
  #endif
 }}}

 The change is needed in order to avoid compilation errors about redefined
 exact_[un]signed_base_helper.

 The condition
 {{{
 ( !defined __TI_COMPILER_VERSION__ || \
                 ( __TI_COMPILER_VERSION__ >= 7000000 && !defined
 __TI_40BIT_LONG__ ) )
 }}}
 excludes cases, where sizeof(long)==8, but long the compiler treats it as
 a 40-bit integer.

 So I thought maybe this could be resolved once and for all ;-)

 Cheers Kris
