[xml] Compilation error on MacOS with -with-minimum option

["Prashanth R" <ramapra gmail com>]

I am trying to build libxml2 (2.7.1.2) static lbrary. 

I was able to build with the options as I needed only SAX2 . 

./configure --prefix=${SRCROOT}/../build/debug --disable-shared --disable-ipv6 --without-catalog --without-debug  --without-docbook --without-fexceptions --without-ftp --without-history --without-html  --without-http  --without-iconv --without-legacy --without-mem-debug - --with-output  --with-push --without-python --with-reader --without-readline --without-regexps --without-run-debug --without-sax1  --without-valid --without-xinclude --without-xpath --without-xptr --without-xpath --without-modules --without-zlib --without-coverage

To reduce the size of my build , I tried to include the -with-minimum=yes that throws 4 errors 

./configure --prefix=${SRCROOT}/../build/debug --enable-static --disable-shared --with-minimum=yes

runxmlconf.c:160: error: syntax error before 'ctxtXPath'

runxmlconf.c:179: error: invalid type argument of '->'

runxmlconf.c:160: error: syntax error before 'ctxtXPath'

runxmlconf.c:179: error: invalid type argument of '->'

Any ideas to why this would happen ?
