* mingw-w64-headers/crt/float.h (FLT_EPSILON,DBL_EPSILON,LDBL_EPSILON): Add
symbols.
* mingw-w64-headers/crt/stat.h (S_ISLNK,S_ISSOCK,S_ISUID,S_ISGID,S_ISLINK):
Add symbols.
(lstat): Add function.
* mingw-w64-headers/crt/_mingw_stat64.h: Likewise
* mingw-w64-headers/crt/stdlib.h (realpath): Add function.
