I have some sympathy for this problem but I tend to think that it's
unreasonable to expect unifdef to work with an incomplete compiler
installation.

The Linux kernel currently has unifdef-2.5. Version 2.6 has better error
handling so it uses the declaration of errno but not any of the E*
values. I could perhaps rejig it to avoid this if it really is important
to be able to bootsrap a system with incomplete headers.
