compiling octave 3.2.4 under Solaris 9

Hi,
I've been trying to compile the latest octave under Solaris 9, but it seems
the frexpf function is missing. With Sun Studio 12, I get:

CC -c -I/usr/local/include -KPIC -I. -I.. -I../liboctave -I../src
-I../libcruft/misc  -DHAVE_CONFIG_H   -g -D_REENTRANT  lo-mappers.cc -o
pic/lo-mappers.o
"lo-mappers.cc", line 498: Error: The function "frexpf" must have a
prototype.

With gcc 4.3.3:

g++ -c -I/usr/local/include -fPIC -I. -I.. -I../liboctave -I../src
-I../libcruft/misc  -DHAVE_CONFIG_H  -Wall -W -Wshadow -Wold-style-cast
-Wformat -g -O2 -D_REENTRANT -pthreads lo-mappers.cc -o pic/lo-mappers.o
lo-mappers.cc: In function 'float xlog2(float, int&)':
lo-mappers.cc:498: error: 'frexpf' was not declared in this scope

Is Solaris supported? Is there any workaround? Would it work better with
Solaris 10?
