dash hangs when it executes cmake

[Silvan Scherrer]

when building cmake with our rpmbuild-bot and using dash as the default shell I see the following:
cmake finishes bootstrapping w/o problems, but the following make hangs completely. make calls cmake with some parameters.

when I do the exact same with ash as the default shell all works as it should.

I tried to debug this part a bit further. But somehow not even the first printf() right after main() is seen. I added fflush(stdout), to be sure it should be seen.

why cmake hangs is now clear. The problem is the driveletter.
The below snippet executed with sh hangs.

cd 'e:/Trees'
cd 'cmake'
cd build

e:/Trees/cmake/build/Bootstrap.cmk/cmake --help

exit 0

While this snippet works. The only difference is the big letter E in the drive part of cd

cd 'E:/Trees'
cd 'cmake'
cd build

e:/Trees/cmake/build/Bootstrap.cmk/cmake --help

exit 0

This behavior is confirmed by different developers.
We now suspect it might be a fork issue.

Changing

%_topdir f:/temp/build

in %HOME%\.rpmmacros to

%_topdir F:/temp/build

fixed the script generation for me and makes cmake work again.
