[GRASS5] Small fix for newer gccs (e.g. 2.95.2)

[Bernhard Reiter]

Found and fixed a small problem which is only hit by newer gccs.
It prevented me to compile the FreeGIS .src.rpm on the GNU/Linux/PPC
system here, which runs gcc 2.95.3 now.

RCS file: /grassrepository/grass/src/libes/geom/basic/cb_doprnt.c,v

Using the type "char" for va_arg() is illegal in standard C.
Therefore I changed it to "int".
