How big archives did You uncompress?

I had ramdrive with size 4Mb, but size of development snapshot of
egcs-1.1 is more than 11Mb in archived form and I was unable to unpack it
when TMPDIR were set to ramdrive. There were no problem to unpack 
libg++ sources where archive size were about 750K.

TAR works ok with small .tar.gz archives when ramdrive with such size 
is being used. The problem is only with big archives. 

Therefore I suggested to modify DJGPP.ENV to tell TAR not to use ramdrive.

However I'm afraid there are problems also with BASH when using pipes:
	some_cmd1 | some_cmd2
perhaps will fail if output of some_cmd1 will not fit in drive specified
with $TMPDIR.
