- ./configure --enable-mtcp-proc-maps    ADDED
  With this, MTCP will use proc/*/maps instead of linker script to discover
    memory region occupied by libmtcp.so
  o NOTE:  This breaks 'make check-openmpi', although manual test still works.
           I don't know why.  To be investigated later.
- fegetround/fesetround moved in mtcp.c to be called when user threads stopped
- minor polishing

- For i386 (32-bit x86), we now create PIC for libmtcp.so when configured
  with --enable-mtcp-use-proc-maps
   + All other architectures already use PIC for libmtcp.so
   + After DMTCP-1.2.5 release, PIC for libmttp.so will be the default;
     but right now it's too close to the release to modify for everybody.

  checkpoint image.  (Thanks to Rohan Garg for finding this.)
