Well, uudeview can handle MIME messages, uuencode, xxencode, base64,
and probably more.

Search the web for it, or check your favourite local FTP site for it.

There is the "metamail" (or mm2.7) toolset on many ftp-servers.
One part is the wanted decoder.

Try this bit of C

--------------------------Start-----------------------
/* base64 decoder */
/* J C Sager, May 1995 */

#include <stdlib.h>
#include <stdio.h>
#include <ctype.h>

char chartab[] = {
-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,
-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,
-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,62,-1,-1,-1,63,
52,53,54,55,56,57,58,59,60,61,-1,-1,-1,-2,-1,-1,
-1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,10,11,12,13,14,
15,16,17,18,19,20,21,22,23,24,25,-1,-1,-1,-1,-1,
-1,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,
41,42,43,44,45,46,47,48,49,50,51,-1,-1,-1,-1,-1};

main()
{
int i, cc, t, padcount;
int state;
union {
int i;
char c[4];
} out;

out.i = 0;
state = 0;
padcount = 0;
while ((cc=getchar()) != EOF)
if (!isspace(cc)) {
if ((t=chartab[cc&0x7f]) == -1) {
printf("Unrecognised input char 0x%02x\n", cc);
exit(1);
}
if (t==-2) /* end padding */
padcount++;
else {
out.i = out.i<<6 | t;
if (++state == 4) {
state = 0;
for (i=1; i<4; i++)
putchar(out.c[i]);
}
}
}

/* finished - sort out the final chars */
if (padcount == 1)
putchar(out.c[2]);
if (padcount > 0)
putchar(out.c[3]);
}

--------------------End----------------------

Then call it like base64 <infile >outfile
