From the documentation for -Xa: The -X options cannot be used if the -std has been specified. The -X options specify varying degress of compliance to the 1990 and 1999 ISO C standard. ... -Xa ISO C plus K&R C compatibility extensions with semantic changes required by ISO C. Where K&R C and ISO C specify different semantics for the same construct, the compiler uses the ISO C interpretation. If the -Xa option is used in conjunction with the -xtransition option, the compiler issues warnings about the different semantics. The default mode for the compiler is -std=c11. > Do AWT folk need to check this. I find it hard to understand the connection between: > > -xc99=nolib > > and > > -DXPG6 > > ?? I was wondering the same thing about -DXPG6.
