Unfortunately, in my case I either seem to get one of these problems or 
the other depending on which solution I try!

Without setting the GCC_EXEC_PREFIX or COMPILER_PATH variables, the 
compiler does seem to use the correct built-in specs for 
my cross-development configuration. However, using the -v option shows 
that these seem to be applied recursively to invocations of CPP until DOS 
memory is exhausted.

According to the GCC documentation, the GCC_EXEC_PREFIX is used for 
finding files such as 'crt0.o' during linking. Is this documentation out 
of date?

I was hoping to avoid building the tools with an absolute path so that 
they could be installed on different drives. I believe the DJGPP DOS 
binaries are configured with relative paths but seem to work correctly 
when invoked from another drive.
