I have tried to configure brexx-2.1.9.tar.gz on WinXP Pro SP3 installed on
VMware using stock DJGPP 2.04 toolchain.  This means I always use the latest
ports of everthing; especially bsh205bbr3.  I started the configure script
without any options.  Sometimes the configuration dies with the following
error message:

[snip]
checking for strstr... yes
configure: creating ./config.status

malloc: dispose_cmd.c:226: assertion botched
free: start and end chunk sizes differ
Stopping myself...Abort!

It is very difficult to reproduce because if I start the script a second time
the configuration may finish successfully producing and running the config.status
script.  A comparision of the config.status files produced when the configuration
passes successfully and the case when the configuration fails shows that sometimes
they are identical and sometimes they are not.  Starting the complete config.status
alone produces the required Makefiles and headers.


I replaced bsh205bbr3 with bsh205bbr2 and I had no longer this fealure.  Please
note that I tried only ten times to configure the sources using bsh205bbr2 so
there is no guarantee that replacing the bashes will really solve the issue.


Anyway, compiling the sources out-of-the-box does not work because it requires
wcslen that is not provided by djgpp so I think that a closer look to th whole
source code may be required.

Please note that I will not be able to solve the bash problem.  In the end we
need a port of  the current bash version and this will be a mayor job.
