  44 # XPG6MODE:  Depending on the version of the compiler, the value of
  45 # __STDC_VERSION__ may differ even in the presence of the same compilation
  46 # options. The default compilation mode for Sun compilers that support the
  47 # C99 standard is -xc99=all,no_lib. C99MODE= is equivalent to -xc99=all,no_lib.
  48 # This translates to C99 semantics without the C99 library specific behaviors
  49 # and dependencies.
  50 #
  51 # For pre-5.7 compilers (unless patched with 117551-04 or 117552-05), in the
  52 # default compilation mode, __STDC_VERSION__ was defined to be 199901L. For
  53 # 5.7 and on compilers, __STDC_VERSION__ defaults to 199409L in order to 
  54 # maintain source compatibility. Neither of these cases results in the 
  55 # importing of /usr/lib/values-xpg6.o, so we need to either manually import 
  56 # it via linking with a local version of the object, or set -xc99=%all which
  57 # by default imports /usr/lib/values-xpg6.o. C99MODE=C99_ENABLE is equivalent
  58 # to -xc99=all. If C99_ENABLE is defined and we also attempt to link with a 
  59 # local version of values-xpg6.o, an error will occur due to multiple 
  60 # definitions for __xpg4 and __xpg6. Because /usr/lib/values-xpg6.o was
  61 # delivered in Solaris 10 and is a stable interface, there is no need to
  62 # build and link with a local version of the object.
  63 #
  64 # The gcc compiler behaves differently and requires -std=gnu99.
  65 #
  66 # For XPG4, we need to link with a local version of values-xpg4.o because
  67 # the compiler only imports this by default (from /usr/lib/values-xpg4.o)
  68 # if we use the c89 utility as opposed to cc.
