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. 惛搙偑棊偪偰偄傞壜擻惈偑偁傝傑偡丅
: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)
or option "-wce=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. 婰壇僋儔僗傑偨偼宆偑巜掕偝傟偰偄傑偣傫
: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
.errgood
auto i;
.eerrgood
is a valid declaration, as is
.errgood
short i;
.eerrgood
However,
.errbad
i;
.eerrbad
is not a correctly formed declaration.
:MSGSYM. ERR_SYMBOL_NAME_TOO_LONG
:MSGTXT. Symbol name truncated for '%s'
:MSGJTXT. 僔儞儃儖柤偑'%s'偵愗幪偰傜傟傑偟偨
:WARNING. 1
.np
Symbol is longer than the object file format allows and has been truncated
to fit. Maximum length is 255 characters for OMF and 1024 characters for
COFF or ELF object files.
:MSGSYM. ERR_SHIFT_AMOUNT_NEGATIVE
:MSGTXT. Shift amount negative
:MSGJTXT. 僔僼僩検偑晧偱偡
:WARNING. 1
.np
The right operand of a left or right shift operator is a negative value.
The result of the shift operation is undefined.
:errbad.
int a = 1 << -2;
:eerrbad.
The value of 'a' in the above example is undefined.
:MSGSYM. ERR_SHIFT_AMOUNT_TOO_BIG
:MSGTXT. Shift amount too large
:MSGJTXT. 僔僼僩検偑戝偒夁偓傑偡
:WARNING. 1
.np
The right operand of a left or right shift operator is a value greater than
or equal to the width in bits of the type of the promoted left operand.
The result of the shift operation is undefined.
:errbad.
int a = 1 >> 123;
:eerrbad.
The value of 'a' in the above example is undefined.
:MSGSYM. ERR_COMPARE_UNSIGNED_VS_ZERO
:MSGTXT. Comparison equivalent to 'unsigned == 0'
:MSGJTXT. 斾妑偺寢壥偼忢偵%d偱偡
:WARNING. 1
.np
Comparing an unsigned expression to see whether it is <= 0 is equivalent to
testing for == 0.
Check to see if the expression should be signed instead of unsigned.
:MSGSYM. ERR_FUNCTION_STG_CLASS_REDECLARED
:MSGTXT. Extern function '%s' redeclared as static
:MSGJTXT. 奜晹娭悢'%s'偼static偲偟偰嵞愰尵偝傟傑偟偨
:WARNING. 1
.np
The specified function was either explicitly or implicitly declared as
.kw extern
and later redeclared as
.kw static.
This is not allowed in ISO C and may produce unexpected results with ISO
compliant compilers.
:errbad.
int bar( void );

void foo( void )

    bar();

:MSGJTXT. 僼傽僀儖偺嵟屻偵夵峴暥帤偑偁傝傑偣傫
:WARNING. 1
ISO C requires that a non-empty source file must include a newline character
at the end of the last line. If no newline was found, it will be automatically
inserted.

: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

for the symbol.
