alloca.h has no define for NULL

The alloca.h header in QNX7 is using NULL but has no #define for it.

This causes compilation failure when no other system header is include:
alloca.cpp:44:5: error: 'NULL' was not declared in this scope

This occurs in Qt configure tests which tests for presence of alloca()

Re: alloca.h has no define for NULL

You are correct. The header should not be using NULL.
