Compiling apache 1.3.6 with php 3.0.9 fails as follows:

I was able to compile okay with php 3.0.7.  php configure
line was:

./configure --with-mysql --with-apache=../apache_1.3.6

As near as I can tell, Unixware does not have "xmalloc" in any library.

Removing alloca.o from the libmodphp3.a library allows apache to compile.
