Full transcript from WebCoreGenerated project

After <http://trac.webkit.org/changeset/46060> a number of people at Apple are
seeing an error during WebCoreGenerated that causes WebCore to fail to build. 
Some relevant snippets from the build log are as follows (a more complete log
is attached):

16>Creating hashtable for
/home/Jessie/OPENSO~1/WebCore/bindings/js/JSRGBColor.cpp
16>bison -d -p cssyy /home/Jessie/OPENSO~1/WebCore/css/CSSGrammar.y -o
CSSGrammar.cpp
16>if sort /home/Jessie/OPENSO~1/WebCore/css/CSSPropertyNames.in
/home/Jessie/OPENSO~1/WebCore/css/SVGCSSPropertyNames.in | uniq -d | grep -E
'^[^#]'; then echo 'Duplicate value!'; exit 1; fi
16>touch CSSGrammar.cpp.h
16>touch CSSGrammar.hpp
16>echo '#ifndef CSSGrammar_h' > CSSGrammar.h
16>Invalid switch.
16>cat /home/Jessie/OPENSO~1/WebCore/css/CSSPropertyNames.in
/home/Jessie/OPENSO~1/WebCore/css/SVGCSSPropertyNames.in > CSSPropertyNames.in
16>echo '#define CSSGrammar_h' >> CSSGrammar.h
16>cat CSSGrammar.cpp.h CSSGrammar.hpp >> CSSGrammar.h
16>perl "/home/Jessie/OPENSO~1/WebCore/css/makeprop.pl"
16>echo '#endif' >> CSSGrammar.h
16>rm -f CSSGrammar.cpp.h CSSGrammar.hpp
16># Lower case all the values, as CSS values are case-insensitive
16>gperf -CDEot -L ANSI-C -k '*' -N findColor -D -s 2
/home/Jessie/OPENSO~1/WebCore/platform/ColorData.gperf > ColorData.c
16>perl -ne 'print lc' /home/Jessie/OPENSO~1/WebCore/css/CSSValueKeywords.in
/home/Jessie/OPENSO~1/WebCore/css/SVGCSSValueKeywords.in > CSSValueKeywords.in
16>if sort CSSValueKeywords.in | uniq -d | grep -E '^[^#]'; then echo
'Duplicate value!'; exit 1; fi
16>gperf -CEot -L ANSI-C -k "*" -N findDoctypeEntry -F
,PubIDInfo::eAlmostStandards,PubIDInfo::eAlmostStandards
/home/Jessie/OPENSO~1/WebCore/html/DocTypeStrings.gperf > DocTypeStrings.cpp
16>Duplicate value!
16>make: *** [CSSValueKeywords.h] Error 1
16>make: *** Waiting for unfinished jobs….

A few interesting lines jump out:
16>Invalid switch.
16>Duplicate value!

This doesn't reproduce on the build.webkit.org build bot in a clean build so it
may be in some way related to the differences between the Debug_Internal and
Debug configurations.
