Solaris for one:

  bash-2.05$ uname -a
  SunOS pcnet5 5.8 Generic_108528-12 sun4u sparc SUNW,Ultra-2
  bash-2.05$ type cc
  cc is hashed (/usr/ucb/cc)
  bash-2.05$ type gcc
  gcc is hashed (/usr/local/bin/gcc)
  bash-2.05$ cc -pthread
  cc: unrecognized option `-pthread'
  cc: No input files
  bash-2.05$ gcc -pthread
  gcc: unrecognized option `-pthread'
  gcc: No input files

gcc does have -pthreads and -threads for Solaris, but these are
basically NOOPs (just what we are doing).  They define
-D_REENTRANT -D_PTHREADS for -pthreads and -D_REENTRANT
and -D_SOLARIS_THREADS for -threads.  These do not specify
any libraries to link, just predefines.  FreeBSD doesn't
have anything to predefine, so it is a true NOOP.
