[R] Problem with XML package compilation on AIX

[Marea Bissonnette]

Hi,

I hope someone has seen this problem before.  I am
trying to install the XML package from
http://cran.r-project.org/src/contrib/XML_0.95-6.tar.gz.

Using 

> R CMD INSTALL XML_0.95-6.tar.gz 

I get the following error message:

/usr/vac/bin/xlc_r -I/usr/local/lib/R/include -DLIBXML
-I/opt/freeware/include/libxml2
-DUSE_EXTERNAL_SUBSET=1 -DROOT_HAS_DTD_NODE=1
-DDUMP_WITH_ENCODING=1 -DUSE_XML_VERSION_H=1
-DXML_ELEMENT_ETYPE=1 -DXML_ATTRIBUTE_ATYPE=1
-DNO_XML_HASH_SCANNER_RETURN=1 -DUSE_R=1 -D_R_=1 
-DHAVE_VALIDITY=1 -I. -DLIBXML2=1 -I/usr/local/include
    -O -qstrict -c DocParse.c -o DocParse.o
"DocParse.c", line 113.29: 1506-280 (E) Function
argument assignment between types "const unsigned
char*" and "char*" is not allowed.
and then more of the same on other lines.

Does anyone know what I can do to get this to compile
happy and install?  Any help would be appreciated.

I'll put the full transcript inline below in case that
helps.
