Can I make this change (enum macros colliding with guile macros)

This is a real brainf'kd construct. Something like simulating  
templates but in C but with macros, even though macros are evil. It is  
defined in src/libqof/qof/qofutils.h and might seem so insanely smart  
at first sight, but due to the inherent evil of macros it won't work  
on a larger scale, as you have just encountered. (Note to self: Gosh,  
I really hate C today.)

No, the _() is not the usual gettext macro here but instead it's the  
local name of the macro's argument. It

Unfortunately no because the identifiers are used both as enum values  
and as their string representations and e.g. dialog-print-check.c line  
942 relies on this conversion from the string representation to the  
enum value.

But couldn't the compiler error be fixed by #undef'ing DATE *before*  
these lines in dialog-print-check.c?
