As for your statement.<\/p>\n

The second paragraph says that “C does not strictly prohibit modifying
\n string literals” while compilers do. So should a string literal be
\n modified?<\/p>\n<\/blockquote>\n

Then compilers do not modify string literals. They may store identical string literals as one array.<\/p>\n

As @o11c<\/strong> pointed out in a comment in the Annex J (informative) Portability issues<\/strong> there is written<\/p>\n

J.5 Common extensions <\/p>\n

1 The following extensions are widely used in
\n many systems, but are not portable to all implementations. The
\n inclusion of any extension that may cause a strictly conforming
\n program to become invalid renders an implementation nonconforming.
\n Examples of such extensions are new keywords, extra library functions
\n declared in standard headers, or predefined macros with names that do
\n not begin with an underscore.<\/p>\n

J.5.5 Writable string literals<\/p>\n

1 String literals are modifiable (in which case, identical string
\n literals should denote distinct objects) (6.4.5).<\/p>\n<\/blockquote><\/div>\n
