FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
_Pragma prevents preprocessing of the remainder of the line

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile this code:

#define NOT_A_TOKEN
int oops() _Pragma("foo") NOT_A_TOKEN;


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the code should compile, because NOT_A_TOKEN should be preprocessed away
ACTUAL -
 ~etp% sunc++ oops.cpp
"oops.cpp", line 2: Error: "{" expected instead of "NOT_A_TOKEN".
"oops.cpp", line 2: Error: NOT_A_TOKEN is not defined.
"oops.cpp", line 2: Error: "}" expected instead of EOF.
3 Error(s) detected.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
see above

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
#define NOT_A_TOKEN
int oops() _Pragma("foo") NOT_A_TOKEN;

CUSTOMER SUBMITTED WORKAROUND :
change the whitespace so that the next token is on another line

#define NOT_A_TOKEN
int oops() _Pragma("foo")
     NOT_A_TOKEN;

A macro at the end of _Pragma is not expanded.
In do_macro_expr(), if the token after a _Pragma is an ident,
perform macro expansion.
