Testing issues related to changes made in phobos locally

[Akshat Sharma]

I am currently working on a good first issue in the phobos 
(https://github.com/dlang/phobos) . So to work on that I referred 
to the contribution guide 
(https://wiki.dlang.org/Contributing_to_Phobos#Full_build) .

As per the guide , the workflow should be as follows :-

1.Fork Phobos on GitHub
2.Create your own branch
3.Work locally on your new feature or fix (see the tips below)
4.Test your improvements locally
5.Submit your pull request (PR)

I was able to complete the first 3 steps , after which I 
installed the DMD compiler (DMD 2.110.0 , windows version) and 
took care of the environment variables, but facing some issues in 
the 4th step . As per the contributing guide , To unittest the 
entire library , we have to run the below given command :

make -j16 -f posix.mak unittest


Unfortunately , it's resulting in the following error :-



$ make -j16 -f posix.mak unittest
posix.mak:1: ===== DEPRECATION NOTICE =====
posix.mak:2: ===== DEPRECATION: posix.mak is deprecated. Please 
use generic Makefile instead.
posix.mak:3: ==============================
C:/Dev-Cpp/bin/make.exe -f Makefile unittest
Makefile:142: Extraneous text after `else' directive

Makefile:146: *** only one `else' per conditional.  Stop.
make.exe[1]: Entering directory `C:/Users/Aman

make.exe[1]: Leaving directory `C:/Users/Aman 
Sharma/Desktop/Dlang_help/phobos'
C:\Dev-Cpp\bin\make.exe: *** [unittest] Error 2



Would appreciate if someone could offer some help . Or by any 
chance is this some bug from phobos ?
