   4 Subject: [PATCH] Don't blindly enable frexpl and ldexpl for uClibc
   5
   6 When the size of double and long double are equal, numpy blindly
   7 assumes that frexpl and ldexpl will be available as well. But for
   8 uClibc, that's not true: it only defines the long double functions
   9 when long double "exists" on the architecture.
  10
  11 So make an exception for uClibc.
