Bug 1219: Sporadic failure to determine 'executable temp base directory'
on Windows using 'exe-windows-i586-268b.bin' (Fix attempt #1)
Replacing the tiny 268 byte sized 'exe-windows-i586-268b.bin' PE file w/
a regular 2048 byte sized PE file 'exe-windows-i386-2048b.bin'.
File is produced via:
 c:\mingw\bin\gcc -nodefaultlibs -nostdlib -s -Os -o tiny.exe tiny.c
Adding the 305 byte sized gzipped version
'exe-windows-i386-2048b.bin.305b.gz' to the gluegen-rt jar file to
reduce the payload for non Windows platforms.
Adding special property 'jogamp.debug.IOUtil.Exe' to debug testing the
exe file, enable via '-Djogamp.debug.IOUtil.Exe'.
Passes here on all Windows machines, however, the prev. one worked here
as well.
