This message would seem to confirm that: http://www.cygwin.com/ml/cygwin/2006-07/msg00758.html > test_complex_h.c: In function `main': > test_complex_h.c:8: error: parse error before "complex" If you change that line this way: - printf("sizeof(%s) = %ld\n", "complex float", sizeof(float complex)); + printf("sizeof(%s) = %ld\n", "complex float", sizeof(float _Complex)); then it compiles, and running it gives sizeof(complex float) = 8 so gcc has some support built in, though the C library doesn't implement the macro defined in C99 7.3.1/2 . It seems to be lacking the complex functions, too: I get undefined reference to `_cexpf' if I try to use cexpf() by providing my own prototype. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
