Makefile:901 error when I trying to compile gcc 5.1 on cygwin

[Hogren]

Hello GCC gurus team !

I hope that all is ok for you today !

I tried to compile the last gcc (v5.1.0) on cygwin. The compilation felt 
good. It spent 2 or 3 hours but… returns an error.

This is the last lines of the compilation (sorry for carrier returns, I 
copy/paste from a small cygwin window):

Makefile:901 : la recette pour la cible « all » a échouée
make: *** [all] Erreur 2
----------


I am french and I can translate "la recette pour la cible « all » a 
échouée" to "the recipe for the target 'all' failed".


It's the first time that I see that.

Someone know the reason of this message ?

Thank you !!
