* NOTE: This implementation is quite strict about requiring all

* field seperators. It also does not allow leading whitespace
|
|
* except when processing the numeric fields. glibc is more
|
|
* lenient. See the various glibc difference comments below.

|
* TODO:
|
|
* Move to dynamic allocation of (currently statically allocated)
|
|
* buffers; especially for the group-related functions since
|
|
* large group member lists will cause error returns.
