The goal is to understand which part of the code is used to determine the stack base, and what it returns. > # grep -E "DINFINITY|DQNAN" * > float.h:#define DINFINITY _DBLINF > float.h: extern unsigned int DQNAN[2]; > float.h:#define DBL_QNAN (*((double *) (DQNAN))) > math.h:#define DINFINITY _DBLINF OK, they are truly declared as ints, which truly breaks strict aliasing rules. Then we should either compile that file with `-fno-strict-aliasing' or not use `-Werror'. >> Our code appears to be based on that of Octave >> (http://hg.savannah.gnu.org/hgweb/octave/file/ec969f3b8955/liboctave/lo-ieee.cc), >> which (erroneously) assumes that these variables are only used on OSF. > AIX is supposed to be compliant with the latest OSF specifications! > If you like you can check out the link below to get more information > about AIX compatability/compliance with UNIX standards. > > http://www-03.ibm.com/systems/p/os/aix/standards/index.html I am roughly assuming OSF == Tru64 (aka. OSF/1). I don't see "OSF" listed in the above page. According to http://en.wikipedia.org/wiki/Open_Software_Foundation, OSF is was merged with the Open Group. Anyway, do you have pointers to documentation or standards that describe `DQNAN' and `DINFINITY'? I don't see anything like this at opengroup.org. >>>net_db.c: In function 'scm_resolv_error': >>>net_db.c:112: warning: implicit declaration of function 'hstrerror' >> >> >> Can you also "rgrep hstrerror /usr/include"? > I did a grep on /usr/include and /usr/include/sys > > # grep hstrerror * > netdb.h:const char *hstrerror(); > netdb.h:const char * hstrerror(int); Is that under /usr/include or /usr/include/sys? Thank you! Ludo'.
