U+02C1 and U+02E4

[Peter Kirk]

What is the difference between U+02C1 and U+02E4? The first is supposed 
to be a miscellaneous phonetic modifier and apparently the pair of 
U+02C0 which marks "ejective or glottalized" (not 1996 IPA). Which 
should be used to mark pharyngealisation (as in 1996 IPA)? This needs to 
be specified somewhere. These two characters are not even linked 
together in the charts.
