Bug#157416: cpp-3.2: _Pragma within macros is improperly expanded

[Andrew Suffield <asuffield@debian.org>]

Package: cpp-3.2
Version: 1:3.2-0pre4
Severity: important

aps100@cyclone:~$ cat foo.c
_Pragma("foo"); int y;
#define FOO _Pragma("foo"); int x;
FOO
aps100@cyclone:~$ cpp-3.2 foo.c
# 1 "foo.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "foo.c"

# 1 "foo.c"
#pragma foo 
# 1 "foo.c"
             ; int y;


# 3 "foo.c"
#pragma ; int x;foo 

The first line is expanded correctly; the third is not (rendering
_Pragma almost completely useless).
