Comment (by marshall):

 Reija --
 I think you should spend a bit more time investigating.
 * What does including ASIO bring to the table - why does it fail when you
 include ASIO (and not when you don't)?
 * Also, what version of Boost are you using?

 The code the compiler is whining about is:
 {{{
 typedef enum { file_begin     = SEEK_SET
              , file_end       = SEEK_END
              , file_current   = SEEK_CUR
              } file_pos_t;
 }}}
 which (given sane values for SEEK_SET, etc) looks fine to me.
 What's the definition of SEEK_SET, etc on your machine?

 Here's the one from my (Mac):
 {{{
 $ grep SEEK_SET /usr/include/stdio.h
 #ifndef SEEK_SET
 #define SEEK_SET        0       /* set file offset to offset */
 }}}

 I'm also wondering about this define in mph/config.h:
 {{{
 /* Force MPICH not to define SEEK_SET, SEEK_CUR, and SEEK_END, which
    conflict with the versions in <stdio.h> and <cstdio>. */
 #define MPICH_IGNORE_CXX_SEEK 1
 }}}
