* error ```c #define csp_without_prefix #include <libcsp/csp.h> #include <unistd.h> ``` ```shell In file included from /usr/local/include/libcsp/csp.h:28, from sum.c:18: /usr/include/unistd.h:1005:13: error: expected identifier or ‘(’ before ‘do’ 1005 | extern void sync (void) __THROW; | ^~~~ /usr/include/unistd.h:1005:13: error: expected identifier or ‘(’ before ‘while’ 1005 | extern void sync (void) __THROW; ``` * But if you reverse the order, it works. ```c #define csp_without_prefix #include <unistd.h> #include <libcsp/csp.h> ``` How can solve this problem? Am i use "csp_async" and "csp_sync" not "sync" and "async". Thankyou for reading this issue
