Ticket #2330 (Ecore.h uses siginfo_t and hence needs to define _XOPEN_SOURCE) created

In file included from /usr/include/elementary-1/Elementary.h:69:0,

/usr/include/ecore-1/Ecore.h: At top level:
/usr/include/ecore-1/Ecore.h:682:4: error: unknown type name ‘siginfo_t’

/usr/include/ecore-1/Ecore.h:972:4: error: unknown type name ‘siginfo_t’

The sigaction manpage says siginfo_t needs _POSIX_C_SOURCE >= 199309L, which in glibc is defined of _XOPEN_SOURCE is defined to 500 or higher (cf. /usr/include/features.h).

I am using ecore-1.7.5 and glibc-2.17.
