|

|

/* This is a simple minded program that tries to find illegal macro
|
||||
definitions in system header files. Illegal macro definitions are
|
||||
those not from the implementation namespace (i.e. not starting with
|
||||
an underscore) or not matching any identifier mandated by The
|
||||
Standard. Some common macro names are considered okay, e.g. all those
|
||||
beginning with E (which may be defined in <errno.h>) or ending in
|
||||
_MAX. See the arrays prefix[] and suffix[] below for details.
|
||||
|
||||
In a compliant implementation no other macros can be defined, because
|
||||
you could write strictly conforming programs that may fail to compile
|
||||
due to syntax errors: suppose <stdio.h> defines PIPE_BUF, then the
|
||||
conforming
|
||||
|
||||
#include <assert.h>
|
||||
#include <stdio.h> <- or where the bogus macro is defined
|
||||
#include <string.h>
|
||||
#define STR(x) #x
|
||||
#define XSTR(x) STR(x)
|
||||
int main (void)
|
||||
{
|
||||
int PIPE_BUF = 0;
|
||||
assert (strcmp ("PIPE_BUF", XSTR (PIPE_BUF)) == 0);
|
||||
return 0;
|
||||
}
|
||||
|
||||
is expected to compile and meet the assertion. If it does not, your
|
||||
compiler compiles some other language than Standard C.
|
||||
|
||||
REQUIREMENTS:
|
||||
This program calls gcc to get the list of defined macros. If you
|
||||
don't have gcc you're probably out of luck unless your compiler or
|
||||
preprocessor has something similar to gcc's -dM option. Tune
|
||||
PRINT_MACROS in this case. This program assumes headers are found
|
||||
under /usr/include and that there is a writable /tmp directory.
|
||||
Tune SYSTEM_INCLUDE and TMPFILE if your system differs.
|
||||
#define BROKEN_SYSTEM if system(NULL) bombs -- one more violation
|
||||
of ISO C, by the way.
|
||||
|
||||
OUTPUT:
|
||||
Each header file name is printed, followed by illegal macro names
|
||||
and their definition. For the above example, you would see
|
||||
...
|
||||
/usr/include/stdio.h
|
||||
#define PIPE_BUF 5120
|
||||
...
|
||||
If your implementation does not yet incorporate Amendment 1 you
|
||||
will see messages about iso646.h, wctype.h and wchar.h not being
|
||||
found. */
