Pruning PATH on GNUstep/MinGW speeds development

[Marcel Weiher]

Hi folks,

one of the problems I've been having with GNUstep on Windows + MinGW is 
that the PATH gets cluttered with tons of paths, most of which do not 
exist.  Especially the non-existent paths seem to slow down command 
execution significantly, but trying to set up fixed paths resulted in a 
non-working environment.

So here's my "set up the GNUstep environment script", extended with a 
couple of lines that prune non-existent directories from the PATH:

---- snip -----
export GNUSTEP_SYSTEM_DIR=/C/GNUstep/System
. $GNUSTEP_SYSTEM_DIR/Makefiles/GNUstep.sh
tempPath=`echo $PATH | sed 's/:/ /g'`
for i in $tempPath ; do if test -d $i; then b=$b:$i;fi  ; done
export PATH=$b
---- snip ----

I am sure this can be done better, but it works for me and seems to 
have cut my framework build times almost in half.

Marcel
