Function Inlining |
 |
Now function inlining happens at all optimization levels,
by default. Functions that should be inlined by the compiler need
to be tagged with the __inline keyword in -Ae mode (inline, in -AC99 mode).
UNIX95 Feature |
 |
Previously, if a search directory specified for -I or -L did not exist or was invalid, the cc driver would ignore it silently and the compilation
would proceed. This is inappropriate, since an incorrect alternate
library or include directory specified on the command line to override
a system one will never be detected.
Now, on encountering a search directory on the command line,
which, either does not exist or has invalid permissions, an error
is flagged and the compilation is aborted. This behavior is applicable
only in strict ANSI mode when either UNIX_STD=95 or UNIX_STD=98 or UNIX95=1 has been set in the environment and only when
the compiler has been invoked as c89.
