Message-ID: <1414234653-18756-1-git-send-email-jcmvbkbc@gmail.com> (raw)
It fixes the following build failure for packages that expect long
double support in libm:
Linking C executable winpr-hash
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `powl'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `fmodl'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `ceill'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `log10l'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `floorl'
