Author: jhibbits Date: Wed Sep 25 14:33:08 2019 New Revision: 352685 URL: https://svnweb.freebsd.org/changeset/base/352685 Log: MFC r342563: libm: Include float.h to get LDBL_MANT_DIG The long double aliases of double functions are only exposed as aliases if LDBL_MANT_DIG is 53 (same as DBL_MANT_DIG). Without float.h included these files were not exposing weak aliases as expected, leading to link failures if programs use the *l functions. This should fix editors/calligra on targets with 64-bit long double, which uses erfl and erfcl. Found on powerpc64.
