Cannot open input icode file \\003323 while invoking compiler

Hello,

i am using the TMS570 toolchain for porting a given application to threadx. The compilation is invoked

by configure and makesfiles from a cygwin shell. Unfortunately the first compiler command

fails with that error message:

> T:/windows/cross/threadx/tms570/ccsv4/tools/compiler/tms470/bin/cl470
> -mv7R4  --diag_warning=225  --enum_type=packed  --elf  --abi=eabi
> --float_support=VFPv3D16  --code_state=32  --preproc_with_compile 
> -IT:/windows/cross/threadx/tms570/ccsv4/tools/compiler/tms470/include 
> -c conftest.c  >> Abort - Cannot open input icode file \\003323: 
> Invalid argument

Searching for that bug i´ve found that link

telling to move the temp folder to a folder without spaces. This workaround did not help for me. Also using the
 ft and fr compiler options did not help. If i invoke the compiler with exactly the same options directly from the cygwin 
shell it works well. But not from the makefile machinery.
