[Alpine-info] qsort Protoype Not Detected Correctly?

[Porcelain Mouse via Alpine-info]

Hello Eduardo & Forum,

Is any one else having problems compiling alpine 2.26 with patch.all, 
recently?  I get a compiler error, see below.

I think the check for the proper arg types for qsort() in sortf() is not 
working correctly.  configure determined that 'char' was the right type, 
but gcc seems to think it's 'void'.  Or, something like that, from what I 
understand.  If I used CFLAGS=-Wno-incompatible-pointer-types, the build 
succeeds.  But, that may not be the best solution.

Related?
