updsvnrev.sh is not fully portable #172
Description
The script updsvnrev.sh, which detects the current revision number fails on
systems, where sh doesn't point to bash (like Ubuntu). The problem is that the
script is called from Makefile using 'sh ...' (for compatibility with Windows
with MinGW), ignoring the shebang in the script itself. Therefore, there is no
simple way to specify that the script should be processed with bash.
This is not critical, since the compilation continues without the revision
number. The possible solution is to replace all bash extensions in the script
(not that much) by POSIX-compliant code.
