Program files environmental variables

[john doe]

Cygwins,

Is there a way to get the value of PROGRAMFILES(x86) and PROGRAMW6432 in
Bash:

$ echo $PROGRAMFILES; echo "$PROGRAMFILES(x86)"; echo $PROGGRAMW6432
C:\Program Files
C:\Program Files(x86)

$ cmd.exe /C "echo %PROGRAMFILES% %PROGRAMFILES(x86)% %PROGRAMW6432%"
C:\Program Files C:\Program Files (x86) C:\Program Files


PROGRAMFILES works in Bash but not the other two.

I could not find anything relevent in the archive or when googling.
