Date: Fri, 13 Apr 2012 19:20:18 -0700 From: Isaac Dunham <idunham@...abit.com> To: musl@...ts.openwall.com Subject: compatability: struct sigaction missing sa_restorer Kernel headers (asm/signal.h) and glibc headers agree that struct sigaction should have sa_restorer; musl provides __sa_restorer This is not mandated in X/Open or POSIX, AFAICT. However, the specification says "struct sigaction includes at least the following members", so here the glibc/kernel approach is conformant, as well as being simple and obvious--as opposed to the possible approach: #ifdef _GNU_SOURCE || _BSD_SOURCE #define sa_restorer .... #endif This prevents building Xvesa; I definitely won't patch it to use __sa_restorer. Don't know if sa_restorer is commonly used. I think that's the last issue, but could be wrong. As far as __[gu]id_t goes: $ grep -r __[gu]id_t /usr/include|wc -l 101 So that's a fair-sized problem (sed already posted, fwiw).
