Alloca isn't declared automagicaly on Solaris 10, breaks build

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use a solaris 10 box
2. python setup.py build
3. gcc complains about no declaration for alloca

What is the expected output? What do you see instead?
continued compilation is expected, actual output looks like this:
gcc -DNDEBUG -g -O3 -m64 -g -I/usr/local/include -fPIC -DPYODBC_VERSION=2.1.8 
-c /tmp/pyodbc-2.1.8/src/getdata.cpp -o 
build/temp.solaris-2.10-i86pc-2.6/tmp/pyodbc-2.1.8/src/getdata.o 
-Wno-write-strings
/tmp/pyodbc-2.1.8/src/getdata.cpp: In function 'PyObject* 
GetDataDecimal(Cursor*, Py_ssize_t)':
/tmp/pyodbc-2.1.8/src/getdata.cpp:401: error: 'alloca' was not declared in this 
scope
error: command 'gcc' failed with exit status 1

What version of the product are you using? On what operating system?
2.1.8 on Solaris 10

Please provide any additional information below.

I see that a macro called __SUN__ is being tested now, but it doesn't appear to 
be defined on a solaris box:

Py_ssize_t)':
/tmp/pyodbc/src/getdata.cpp:401: error: 'alloca' was not declared in this scope
