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