Hi folks,
Latest c-ares build failing with gcc 12.4 and Cygwin 3.6.0 header:
$ uname -srvmo
CYGWIN_NT-10.0-19045 3.6.0-1.x86_64 2025年03月18日 17:01 UTC x86_64 Cygwin
$ gcc --version

/usr/include/sys/unistd.h:218:14: error: expected ';' before 'void'
 218 | static inline void setproctitle_init (int _c, char *_a[], char *_e[]) {}
 | ^~~~~

$ ll -gG /usr/include/sys/unistd.h

215 #if defined(__CYGWIN__) && __BSD_VISIBLE
216 /* Stub for Linux libbsd compatibility. */
217 #define initsetproctitle(c, a, e) setproctitle_init((c), (a), (e))
218 static inline void setproctitle_init (int _c, char *_a[], char *_e[]) {}
219
220 void setproctitle (const char *, ...)
221 _ATTRIBUTE ((__format__ (__printf__, 1, 2)));
222 #endif
...
includes latest fix to definition; also tried with original definition.
Not seeing any obvious issues with storage class and type specifiers mentioned.
For now, build working with !defined(__CYGWIN__) hack.
No problem with other builds! Ideas welcome ;^>
