Helena,

to make it compile, I have applied the following change in CVS:

RCS file: /grassrepository/grass51/lib/rst/interp_float/interpf.h,v
retrieving revision 1.5
diff -u -r1.5 interpf.h
--- interpf.h   14 Dec 2004 04:06:07 -0000      1.5

Not sure if it's right but now it compiles.


My suggestion is to use the following CFLAGS to catch such
problems:

export CFLAGS='-g -Wall -Werror-implicit-function-declaration -fno-common'
configure ...
make
