problems compiling in solaris 10

Hi,

I'm compiling HEAD on solaris 10 and i'm getting this warning

"""
float.c: In function ‘is_infinite’:
float.c:201:2: warning: implicit declaration of function ‘isinf’
[-Wimplicit-function-declaration]
int inf = isinf(val);
^
geo_ops.c: In function ‘pg_hypot’:
geo_ops.c:5459:2: warning: implicit declaration of function ‘isinf’
[-Wimplicit-function-declaration]
if (isinf(x) || isinf(y))
^
timestamp.c: In function ‘float8_timestamptz’:
timestamp.c:722:2: warning: implicit declaration of function ‘isinf’
[-Wimplicit-function-declaration]
if (isinf(seconds))
^
execute.c: In function ‘sprintf_double_value’:
execute.c:466:2: warning: implicit declaration of function ‘isinf’
[-Wimplicit-function-declaration]
else if (isinf(value))
^
"""

reason seems to be that solaris define isinf() inside iso/math_c99.h
(which is included by math.h) and only if __C99FEATURES__ is defined.
and yes, adding 'CFLAGS="-D __C99FEATURES__" does that warning to go

------

another problem i found is that if i configure using
--enable-profiling then error is raised:

"""
checking thread safety of required library functions... no
configure: error: thread test program failed
This platform is not thread-safe. Check the file 'config.log' or compile
and run src/test/thread/thread_test for the exact reason.
Use --disable-thread-safety to disable thread safety.
"""

seems there is a segmentation fault when trying to compile the test,
attached is config.log
