nsExec::ExecToLog 'attrib.exe -r "$INSTDIR\*.*" /s'
accomplishes the same thing. attrib.exe should be available and in the path of any Windows machine ever.
I was looking for a recursive version of Attrib and bumped across this : http://nsis.sourceforge.net/RecFind:_Recursive_FindFirst%2C_FindNext%2C_FindClose

${RecFindOpen} $1 $R0 $R1
${RecFindFirst}
IfFileExists "$R0\$R1\*.*" Found

Calling this using the same syntax as the original Attrib function, that is :
Push $INSTDIR\ Call RecursiveAttrib
does the action (SetFileAttributes) on the files recursively.
Advantages I find :
- no dependency on attrib.exe (although it should be there 99.9% of the time)
- no ugly black cmd.exe flashing during the install process
- possibility of doing some other operation than setting file attributes
