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.
