Please keep in mind that only the GCC packages shipped in the distribution (currently, 6.4.0) are supported here.

Any > help appreciated. crypt_r and struct crypt_data are GNU extensions and therefore, just like with glibc, requires _GNU_SOURCE in order to compile. perl must be defining _GNU_SOURCE with glibc in order for this to compile there; perhaps it just needs to know that we require it as well. > When i was under cygwin 2.8.2, everything was ok. crypt is separate from the cygwin package. crypt was completely reimplemented a few weeks ago to include new features. -- Yaakov
