Ensure that directory is created before its written to
This can cause a build race in a highly parallelised build where a directory is not yet
created but
output file is being written using redirection e.g.
rst2man.py --strict --no-raw --no-generator --no-datestamp < ../git/monitor/iwmon.rst
> monitor/iwmon.1
/bin/sh: monitor/iwmon.1: No such file or directory

New subject: [PATCH V2] Makefile.am: Avoid redirection of input and output
files
Hi Khem,
Ensure that directory is created before its written to
This can cause a build race in a highly parallelised build where a directory is not yet
created but
output file is being written using redirection e.g.
rst2man.py --strict --no-raw --no-generator --no-datestamp < ../git/monitor/iwmon.rst
> monitor/iwmon.1
/bin/sh: monitor/iwmon.1: No such file or directory
make[1]: *** [Makefile:3544: monitor/iwmon.1] Error 1

sorry for looking at this so late, can you send me a version that applies to the latest
HEAD.
