It looks like you didn't delete your old version before
installing the new one.  In one of the 3.0 WIPS the field
`line_offset' got changed to `y_offset' and a `x_offset' was
also added.  This has made problems for you because during the
build process Allegro creates and runs a program called `asmdef'
which generates a header file for use in assembly language files
that helps the assembly language routines deal with structures,
by telling them the offsets of various fields. There is no such
thing as an `implicit declaration' in assembly language, so the
fact that this macro should have been changed from
`BMP_LINEOFFSET' to `BMP_YOFFSET' wasn't noticed.  The main
thing you need to do is rebuild the helper header file.

It's much safer though for you to rebuild the whole thing.
Provided you don't have any custom modifications or addons in
subdirectories, just delete your Allegro directory completely
and reinstall it.
