configure: check for sgml to texi tools fails with OpenSP

[John Clizbe]

Last night I was building a svn rev of 1.4.10 on my Slackware box. Going over
the output from configure, I thought it odd the the test for sgml to texi tools
was failing. OpenSP 1.5.2 is installed, sgml2xml is present:

    bear at yogi:~/gnupg14r4834# sgml2xml -v
    sgml2xml:I: "OpenSP" version "1.5.2"

OK, so OpenSP is wrapping things in double-quotes

Here's a patch...

bear at yogi:~/gnupg14r4834# diff -u acinclude.m4{~,}

     if test "$ac_cv_prog_DOCBOOK_TO_TEXI" = yes; then

             working_sgmltotexi=yes
+      elif sgml2xml -v /dev/null 2>&1 | grep 'OpenSP\" version' >/dev/null 2>&1
; then
+            working_sgmltotexi=yes
       fi
     fi
     AC_MSG_RESULT($working_sgmltotexi)

Sorry about the elif line wrapping

The same test fails on Cygwin, but that's an issue with their build of OpenSP.

Best,

John
