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

||
