[Dlang-internal] Cannot build dmd from git going from v2.78.3

[Patrick Schluter]

Hi,

I have a problem with the dmd git repository. I cannot compile de 
compiler for versions newer than v2.78.2.
I can build every version up until v2.78.2. When I try to build 
v2.78.3 I get following error message:

CC="c++" dmd -lib -of../generated/linux/release/64/lexer.a -m64 
-J../generated/linux/release/64 -L-lstdc++ -version=MARS -fPIC -w

make[1]: Leaving directory 
`/ec/dev/server/euramis/u000/schlupa/D/dmd/src'
make: *** [all] Error 2
error: make failed

Does anyone have an idea what can be wrong? Is something missing 
somewhere?


PS: the machine this is built on is an old Linux RHEL 5 which 
config is stuck to what it was when it initially came out. I 
don't have sudo or root access on it and all tools and programs I 
need have to be built from source, either from packets or git 
repos. Installing ready made binaries does not work in general.
I know, it sucks but I cannot change the policies of our IT 
environment.
