The inclusion of any extension that may cause a strictly conformingprogram to become invalid renders an implementation nonconforming. Examples of suchextensions are new keywords, extra library functions declared in standard headers, orpredefined macros with names that do not begin with an underscore.J.5.1 Environment arguments1In a hosted environment, the main function receives a third argument, char *envp[],that points to a null-terminated array of pointers to char, each of which points to a stringthat provides information about the environment for this execution of the program(5.1.2.2.1).J.5.2 Specialized identifiers1Characters other than the underscore _, letters, and digits, that are not part of the basicsource character set (such as the dollar sign $, or characters in national character sets)may appear in an identifier (6.4.2).J.5.3 Lengths and cases of identifiers1All characters in identifiers (with or without external linkage) are significant (6.4.2).J.5.4 Scopes of identifiers1A function identifier, or the identifier of an object the declaration of which contains thekeyword extern, has file scope (6.2.1).J.5.5 Writable string literals1String literals are modifiable (in which case, identical string literals should denote distinctobjects) (6.4.5).J.5.6 Other arithmetic types1Additional arithmetic types, such as _ _int128 or double double, and theirappropriate conversions are defined (6.2.5, 6.3.1).
Additional floating types may havemore range or precision than long double, may be used for evaluating expressions ofother floating types, and may be used to define float_t or double_t.§J.5.6Portability issues513ISO/IEC 9899:TC3Committee Draft — Septermber 7, 2007WG14/N1256J.5.7 Function pointer casts1A pointer to an object or to void may be cast to a pointer to a function, allowing data tobe invoked as a function (6.5.4).2A pointer to a function may be cast to a pointer to an object or to void, allowing afunction to be inspected or modified (for example, by a debugger) (6.5.4).J.5.8 Extended bit-field types1A bit-field may be declared with a type other than _Bool, unsigned int, orsigned int, with an appropriate maximum width (6.7.2.1).J.5.9 The fortran keyword1The fortran function specifier may be used in a function declaration to indicate thatcalls suitable for FORTRAN should be generated, or that a different representation for theexternal name is to be generated (6.7.4).J.5.10 The asm keyword1The asm keyword may be used to insert assembly language directly into the translatoroutput (6.8).
The most common implementation is via a statement of the form:asm ( character-string-literal );J.5.11 Multiple external definitions1There may be more than one external definition for the identifier of an object, with orwithout the explicit use of the keyword extern; if the definitions disagree, or more thanone is initialized, the behavior is undefined (6.9.2).J.5.12 Predefined macro names1Macro names that do not begin with an underscore, describing the translation andexecution environments, are defined by the implementation before translation begins(6.10.8).J.5.13 Floating-point status flags1If any floating-point status flags are set on normal termination after all calls to functionsregistered by the atexit function have been made (see 7.20.4.3), the implementationwrites some diagnostics indicating the fact to the stderr stream, if it is still open,514Portability issues§J.5.13WG14/N1256Committee Draft — Septermber 7, 2007ISO/IEC 9899:TC3J.5.14 Extra arguments for signal handlers1Handlers for specific signals are called with extra arguments in addition to the signalnumber (7.14.1.1).J.5.15 Additional stream types and file-opening modes1Additional mappings from files to streams are supported (7.19.2).2Additional file-opening modes may be specified by characters appended to the modeargument of the fopen function (7.19.5.3).J.5.16 Defined file position indicator1The file position indicator is decremented by each successful call to the ungetc orungetwc function for a text stream, except if its value was zero before a call (7.19.7.11,7.24.3.10).J.5.17 Math error reporting1Functions declared in <complex.h> and <math.h> raise SIGFPE to report errorsinstead of, or in addition to, setting errno or raising floating-point exceptions (7.3,7.12).§J.5.17Portability issues515ISO/IEC 9899:TC3Committee Draft — Septermber 7, 2007WG14/N1256Bibliography1.‘‘The C Reference Manual’’ by Dennis M.
