I take it the "underlying C" is yours? have you compiled it with
-D_REENTRANT ? (I _think_ that's the Solaris way of saying the
compiler should pick up the thread-aware version of errno and others).

From the Linux <errno.h>,

  #if defined(_POSIX_THREAD_SAFE_FUNCTIONS) || defined(_REENTRANT)
  extern int*	__errno_location  __P((void));
  #define errno	(*__errno_location ())
  #else
  extern int errno;
  #endif
