Hello everyone,
As most devs including me noticed this "the input line is too long" bug after hpoussin's changes in r34187 to r34191, I did some research on it. Unfortunately, it looks like it's unfixable if we keep on directly using ld for linking (as introduced in these revisions) instead of calling the gcc frontend.
First of all, the "length" of the cmd input line under Windows seems to be highly affected by quotation marks. If you add a quotation mark to the working linker command line before hpoussin's commits, it will also be reported as being too long. Previously, we didn't use quotation marks in the command line when linking the binaries. Now we have to do this because of the changed PROJECT_LFLAGS and PROJECT_LPPFLAGS variables: They contain the path to i.e. libgcc and as this path can contain spaces, it has to be put in quotation marks. Just passing "libgcc.a" without a path doesn't work. Passing "-lgcc" also doesn't work, because mingw32-ld only seems to search for libraries in "mingw32/lib", not "lib/gcc/mingw32/4.1.3" as gcc does.
I see no other solution than partly reverting hpoussin's changes and using gcc for linking again. If anyone sees another option, please comment or directly commit a fix.
Best regards,
Colin
