package/popt/0003-glob-detection.patch

   1 Detect glob_pattern_p()
   2
   3 The current popt build system tests the existence of <glob.h>, and
   4 then assumes that if __GLIBC__ is defined, then glob_pattern_p() must
   5 be available. Unfortunately, that's not true with uClibc: <glob.h> may
   6 be installed, but not necessarily the GNU glob extensions... and
   7 uClibc defines __GLIBC__. This is causing build issues with certain
   8 uClibc toolchains that do not have GNU glob extensions enabled.
   9
  10 To fix this, this patch adds an AC_CHECK_FUNCS() test for
  11 glob_pattern_p, and uses that to find out whether glob_pattern_p() is
  12 available or not.
