Just adding to a very old thread - NetBSD tree:

RCS file: /cvsroot/src/lib/libc/net/getaddrinfo.3,v
revision 1.44
date: 2006/07/18 14:00:40;  author: christos;  state: Exp;  lines: +2 -6
Remove comments that do not reflect reality anymore.

that's when the BUGS "danger not threadsafe" section disappeared...


(I just tried to compile freetds-current on netbsd-current
checking whether pthreads work with -pthread... yes
checking for getaddrinfo... yes
checking for getnameinfo... yes
checking threadsafety... enabled
and as before
threadsafe.c:393:2: error: #error gethostbyname_r style unknown
threadsafe.c: In function 'tds_getservbyname_r':
threadsafe.c:469: warning: implicit declaration of function 'getservbyname_r'

new:
bsqlodbc.c:49:17: error: sql.h: No such file or directory
bsqlodbc.c:50:20: error: sqlext.h: No such file or directory

quibble: in src/odbc/Makefile.am is the gnu make specific pattern
%.res: %.rc really necessary?)

Cheers,

Patrick
