Compiling grass on GNU/Linux, Debian - potato:

GISGEN failure at STEP: src/mapdev/v.in.dlg
make: *** [do-install] Error 1
The offending code redefines ANSI C functions/macros pow() and strchr():
From r_dlg_head.c
<SNIP>
184 static int _get_dtype(char *buf, double *doub)
185 {
186 char *strchr() ;
187 double raise ;
188 double pow() ;
189 int pwr ;
190
191 *doub = 0.0 ;
192 raise = 10.0 ;
193 pwr = 0 ;
194 sscanf(buf,"%lf", doub) ;
195 if (*doub != 0.0)
196 {
197 /* sscanf(strchr(buf,'D')+1,"%d", &pwr) ; */
198 char *p;
199 if ((p = G_index (buf, 'D')) != NULL)
200 sscanf(p+1, "%d", &pwr);
201
202 }
203 if (pwr)
204 {
205 *doub = *doub * pow(raise, (double)pwr) ;
206 }
207
208 return 0;
209 }
</SNIP>
This problem is fixed (for compilation at least) by commenting out
lines 186 and 188.
