Or not compiling freeciv that often ... very easy and fast solution.

  x x<M> Simplified Chinese charset (CP936, GB2312)
  x x<M> Korean charset (CP949, EUC-KR)

  CC [M]  fs/nls/nls_cp936.o
  CC [M]  fs/nls/nls_cp949.o

and < 20 MB RAM ... i don't think that compare the size from the 
source-files helps.

38 MB was max for the for the scsi drivers.

And the kernel needed ~38 MB several times for other files.

Yes, but it is no problem.
