Thanks, but under /usr/sbin/ should be a script like download_ecj.sh
for downloading and installing, but in my Cygwin version the script
does not exists

If I try to compile a java code with "gcj mysource.java" I get the error:
/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../libcygwin.a(libcmain.o):(.text+0xa9):
undefined reference to `_WinMain@16'
collect2: ld returned 1 exit status
How can I solve the linker problem? (I have installed the newest
version of Cygwin)
Thanks
Phil
