In the preprocess command block #ifdef to #endif, which performs the condition compile, I get an error when I describe a double

quotation. Why? I don't get an error for any other character.

I assume that if the respective identifier is macro-defined with #ifdef, the operation will not progress.

The NC79WA performs the #ifdef analysis after the token analysis. Therefore, the NC79WA will generate an error if the following

statement is enclosed in quotations.

#ifdef NEVER

" /*double quotation marks*/

#endif

Reference info:

The NC79WA specification is construction so that ANSI is dependent on the compiler (in other words, undefined). The

results from other compilers are as described below. As understood from these results, operations differ according to the

compiler.

(1) Will the next source be an error?

#ifdef NEVER

" /*double quotation marks*/

#endif

SUNOS cc no error

Solaris cc no error

gcc -traditional-cpp no error

gcc error

("unterminated string or character constant")

ncXXwa error

("new_line in string")

(2) Will the next source be an error?

#if 0

/* comment

#endif

SUNOS cc error

("missing */")

Solaris cc no error

("Warning: this file closed during the comment")

gcc -traditional-cpp error

("unterminated comment")

gcc error

("unterminated comment")

cpp30 error

("EOF in comment")
