    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: Other
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general

portability patch for configure.ac

Configuring poppler-0.20.2 in a separate object dir failed for me on Solaris
with the following error message:

/vol/src/X11/poppler/poppler-0.20.2/configure: syntax error at line 23951: `('
unexpected

This is due to the (wrong) assumption, that /bin/sh is always a bash. On
Solaris (at least), /bin/sh is a real Bourne Shell and therefore does not know
about $(...) command substitutions.

The attached patch resolves this issue by replacing the $(...) command
substitution with the more portable backtick evaluation.
