Re: Win32 Make

these functions must be checked using check_symbol_exists

I have changed CMakeLists.txt as follows:

==============================================
# find functions
set(CMAKE_REQUIRED_LIBRARIES ${CMAKE_THREAD_LIBS_INIT})
set(FUNCS _atoi64 strtok_r readpassphrase
	strlcpy strlcat basename getopt strsep gettimeofday
	nl_langinfo locale_charset setenv putenv
	getuid getpwuid getpwuid_r fstat alarm fork
	gethrtime localtime_r setitimer
	_fseeki64 _ftelli64 setrlimit
	inet_ntoa_r getipnodebyaddr getipnodebyname
	getaddrinfo inet_ntop gethostname poll socketpair
	clock_gettime fseeko pthread_cond_timedwait
	pthread_condattr_setclock _lock_file _unlock_file usleep nanosleep
	readdir_r)

foreach(func ${FUNCS})
	string(TOUPPER "HAVE_${func}" var)
	check_function_exists(${func} ${var})
	set(HAVE_GETADDRINFO 1 CACHE INTERNAL "")
	config_write("/* Define to 1 if you have function <${func}>. */\n")
	config_write("#cmakedefine ${var} 1\n\n")
endforeach(func)

set(VSPRINTF asprintf vasprintf vsnprintf _vsnprintf snprintf _snprintf _vscprintf)

foreach(func ${VSPRINTF})
	string(TOUPPER "HAVE_${func}" var)
	check_symbol_exists(${func} stdio.h ${var})
	config_write("/* Define to 1 if you have function <${func}>. */\n")
	config_write("#cmakedefine ${var} 1\n\n")
endforeach(func)

set(CMAKE_REQUIRED_LIBRARIES)
==============================================

This works for the replacement functions but runs into an error when linking tdsodbc.dll because some stdio functions 
seem to have moved to legacy_stdio_definitions.lib

How can this lib be included optional into cmake?
