Hi Magnus,
What did -Xa do?
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.
So basically -std=c89
Thanks,
David
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=no_lib
and
-D_XPG6
??
I was wondering the same thing about -D_XPG6.
