Hello, It could be that snprintf() is not properly declared in <stdio.h>.
Take the following foo.c: % cat foo.c #include <stdio.h> int main(void) { char buf[10]; snprintf(buf, 10, "%i", 0); return 0; } % In C, perhaps after a remark from Markus (http://sourceware.org/ml/cygwin/2009-04/msg00435.html), no compiler message is produced: % gcc -xc -std=c90 -c foo.c % gcc -xc -std=c99 -c foo.c % On the other hand, for C++, a compiler message is produced: % gcc -xc++ -std=c++98 -c foo.c foo.c: In function 'int main()': foo.c:6:28: error: 'snprintf' was not declared in this scope % % gcc -xc++ -std=c++0x -c foo.c foo.c: In function 'int main()': foo.c:6:28: error: 'snprintf' was not declared in this scope % Replacing <stdio.h> with <cstdio> produces the same result. Shouldn't snprintf() (and vsnprintf() etc.) be declared in <stdio.h> also for the C++ language/standard, especially c++0x?
