In VC++, the "#error temp error" directive at line 75 in file "mongo/util/text.h" isn't well interpreted.
This lead to a confusing error C1004:
"src\mongo/util/text.h(75) : fatal error C1004: unexpected end-of-file found"

Using the directive "#error" in an header file could be the result of this weird behaviour. See the report: http://connect.microsoft.com/VisualStudio/feedback/details/757886/c1004-instead-of-c1189-when-error-is-in-a-header

What I suggest is to add a "#pragma warning" before the "#error", like:
"#pragma message (_FILE_": temp error")"
