The handling of backslashes as escaping characters is not the problem,
it seems. If I pass this string (verbatim, just like it is printed here) to
"c:\home\chicken-trunk\bin\csi" -bnq -e "(require-library setup-api)"
-e "(import setup-api)" "c:\...some...path...\defstruct.setup"
I get an error message that tells me that the program
"c:\home\chicken-trunk\bin\csi" -bnq -e ""
(sic) can not be found.
To reproduce the problem, one can do the following:
- checkout the current svn trunk
- run "make PLATFORM=mingw PREFIX=c:/home/chicken-trunk DEBUGBUILD=1
(prefix must contain drive letter and use forward slashes)
- run "make PLATFORM=mingw PREFIX=c:/home/chicken-trunk DEBUGBUILD=1"
- run "make PLATFORM=mingw PREFIX=c:/home/chicken-trunk DEBUGBUILD=1 install"
- run "bin\chicken-install defstruct"
