Bug#2037: bibtex not searching $TEXINPUTS

[Herbert Thielen <Herbert.Thielen@lpr.e-technik.tu-muenchen.de>]

Just noticed this old bug report. In my opinion it's a bug in the
kpathsea library (which is linked statically in bibtex and is not
included in the kpathsea package, but in the kpathsea package source).

You can verify this behaviour by using kpsewhich (included in package
kpathsea):

  ernie:~$ touch /tmp/foo.bst
  ernie:~$ KPATHSEA_DEBUG=8 TEXMFCNF=. TEXINPUTS=/tmp kpsewhich foo.bst
  kdebug:Search path for .cnf files (from TEXMFCNF environment variable)
  [...]
  kdebug:Search path for .bst files (from compile-time paths.h)
  kdebug:  = .:/bibtex/bst:/usr/lib/texmf/bibtex/bst
  kdebug:  before expansion = .:$texmfloc/bibtex/bst:/usr/lib/texmf/bibtex/bst
  kdebug:  font override var applies = 0
  kdebug:  application config file path = (none)
  kdebug:  texmf.cnf path = (none)
  kdebug:  compile-time path = .:$texmfloc/bibtex/bst:/usr/lib/texmf/bibtex/bst
  kdebug:  suffix = .bst
  kdebug:  search only with suffix = 0
  kdebug:  runtime generation program = (none)
  kdebug:  extra program args = (none)

BSTINPUTS gets used correctly:

  ernie:~$ KPATHSEA_DEBUG=8 TEXMFCNF=. BSTINPUTS=/tmp kpsewhich foo.bst
  kdebug:Search path for .cnf files (from TEXMFCNF environment variable)
  [...]
  kdebug:Search path for .bst files (from BSTINPUTS environment variable)
  kdebug:  = /tmp
  kdebug:  before expansion = /tmp
  kdebug:  font override var applies = 0
  kdebug:  application config file path = (none)
  kdebug:  texmf.cnf path = (none)
  kdebug:  compile-time path = .:$texmfloc/bibtex/bst:/usr/lib/texmf/bibtex/bst
  kdebug:  suffix = .bst
  kdebug:  search only with suffix = 0
  kdebug:  runtime generation program = (none)
  kdebug:  extra program args = (none)


ernie:~$ dpkg -l kpathsea
