I agree. It should be so. Perhaps the best would be to modify the macro 
so that it is not broken for other targets and returns correct value
for DJGPP (and submit changes to maintainers of autoconf). Adding DJGPP 
specific changes by us without including them into distribution may 
force us to run autoconf for each package to be configured for DJGPP

Currently only way is to set needed environment variables and only 
after that run configure to override false settings for DJGPP.
Some shell script is best to do this currently (as I think)
