:MSGJTXT. #endif偑懠偺僜乕僗僼傽僀儖'%s'偺#if偲懳墳偟偰偄傑偡
:WARNING. 1
This warning may indicate a
.kw #endif
nesting problem since the traditional usage of
.kw #if
directives is confined to the same source file.
This warning may often come before an error
and it is hoped will provide information to
solve a preprocessing directive problem.
:MSGSYM. ERR_LOSE_PRECISION
:MSGTXT. Possible loss of precision
:MSGJTXT. Possible loss of precision
:WARNING. 1
.np
This warning indicates that you may be converting a argument
of one size to another, different size. For instance, you may be
losing precision by passing a long argument to a function that
takes a short.
This warning is initially disabled. It must be explicitly enabled with
.us #pragma enable_message(130).
It can be disabled later by using
.us #pragma disable_message(130).
:MSGSYM. ERR_ASSUMED_IMPORT
:MSGTXT. No prototype found for function '%s'
:MSGJTXT. '%s'偺僾儘僩僞僀僾偑偁傝傑偣傫
:WARNING. 1
.np
A reference for a function appears in your program, but you do not
have a prototype for that function defined. Implicit prototype will
be used, but this will cause problems if the assumed prototype does
not match actual function definition.
:MSGSYM. ERR_NO_STG_OR_TYPE
:MSGTXT. No storage class or type specified
:MSGJTXT.
:WARNING. 1
.np
When declaring a data object, either storage class or data type must be
given. If no type is specified,
.kw int
is assumed. If no storage class is specified, the default depends on
scope (see the
.us C Language Reference
for details). For instance
.exam begin
auto i;
.exam end
is a valid declaration, as is
.exam begin
short i;
.exam end
However,
.exam begin
i;
.exam end
is not a correctly formed declaration.

There are no references to the declared variable.
The declaration for the variable can be deleted.

:WARNING. 2
.np
The symbol has been used in a preprocessor expression.
The compiler assumes the symbol has a value of 0 and continues.
A
.id #define
may be required for the symbol, or you may have forgotten
to include the file which contains a
.id #define
for the symbol.

There are no references to the declared parameter.
The declaration for the parameter can be deleted.
Since it is a parameter to a function, all calls to the function
must also have the value for that parameter deleted.

In some cases, there may be a valid reason for retaining the parameter.

:WARNING. 3
