There's a more serious problem; src/include/projects.h hasn't been
updated, but the new code won't compile with the existing projects.h
file. The projects.h file from PROJ 4.4.5 can't be used as is, because
there are some GRASS-specific functions which need to be added.

Also, the "UV" structure has been renamed to "projUV", which impacts
upon programs which use the library (primarily v.proj; the other
occurrences are in src.contrib/SCS, in code which appears to be unused
at present).
