Subject: [PATCH] bit fields treating negative values should be declared as
 signed int

* internal.h (struct vm_ifunc_argc): Bit fields are unsigned by default.
  For storing nagative values to bit fields, they must be declated as
  signed int. Fix multiple test failure observed by 32-bit binaries
  compiled with Oracle Developer Studio (Solaris Studio) 12.x on
  Solaris 10 on sparc architecture. [Bug #14260]
