Build error in sqlite-3.6.22 found by randomised testing.

[Dr. David Kirkby]

Following my attempts to build Sage, whilst inserting random delays in front of
gcc/g++/gfortran, an error occured with sqlite-3.6.22.

This rather surprised me, as the sqlite team takes testing very seriously (more
so than Sage),

http://www.sqlite.org/testing.html

with 647 times as much test code as actual source code for the database!

I'm begginging to wonder if building with delays to gcc is either a very good
way to find bugs, or is a totally stupid way. I've built Singular 500 times
without a build error now.

Something is wrong with escaping the quotation marks in the gcc call.
How are you implementing the delay? Are you sure it preserves shell
escapes? If anything it seems to be a bug in the shell or make, but
not sqlite.

Cheers,
Volker

Yes, I realised the problem. I will correct it.
