libposix license

[Bruno Haible]

Hi all,

Among the modules that will be part of libposix, i.e. that are listed as
gnulib modules for some POSIX functions or headers, the following are
currently under GPL license:

<math.h> functions:

  acosl
  asinl
  atanl
  cosl
  expl
  isfinite
  logl
  sinl
  sqrtl
  tanl

File system related functions, around openat() - discussed in another thread -

  getcwd
  faccessat
  fdopendir
  linkat
  mkfifoat
  openat
  readlinkat
  renameat
  symlinkat
  utimensat

<stdio.h> related:

  fflush

Obsolete modules (could be omitted from libposix):

  free
  memcpy

Other modules:

  futimens
  nanosleep

  getgroups

  strtoimax
  strtoumax

  tmpfile

  tzset

If any module in the library is GPL, the entire library is GPL.

What do you think? Should libposix be LGPL or GPL?
