I've opened ticket #2127 with suggested fix:

change line 5657 in ./ltmain.sh (or the correct line in the file it 
originates from) from:

$ECHO "$obj" >> $output

to

$ECHO "$obj" | ${SED} -e 's/.*gdal-[0-9].[0-9].[0-9]/\./' >> $output

(checked on MSYS and Linux RHEL4). Probably there is a better way of 
getting the build directory name - I am building in the source tree rather 
than outside. This is probably too small to be worth a patch, and in any 
case ltmain.sh claims to be the output of ltmain.m4sh.

The export CXXFLAGS=-O2 and export CFLAGS=-O2 route to avoiding large DLLs 
also works on MSYS.
