lfnfor is a new system variable under win95 that makes for work using
long filenames rather than short ones. you can check its status by just
typing lfnfor at the command line. say you have a file prog.c and a
batch file

for %%f in (*.c) do gcc -c %%f

if lfnfor is off, running this batch file will result in:

D:\djgpp\C\TEST\b> type b.bat
for %%f in (*.c) do gcc -c %%f

D:\djgpp\C\TEST\b> b

D:\djgpp\C\TEST\b> for %f in (*.c) do gcc -c %f

D:\djgpp\C\TEST\b> gcc -c PROG.C

hence prog.c will be compiled as C++. you can verify this by adding the
-v parameter to the command line. OTOH:

D:\djgpp\C\TEST\b> lfnfor=on

D:\djgpp\C\TEST\b> b

D:\djgpp\C\TEST\b> for %f in (*.c) do gcc -c %f

D:\djgpp\C\TEST\b> gcc -c prog.c

compile prog.c as C.
