I'm trying to build the master branch of DMD on redhat 7.
I get the following errors:

ddmd/root/newdelete.c:26:8: error: expected identifier or ‘(’ before string constant
 extern "C"
        ^
ddmd/root/newdelete.c:31:17: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘new’
 void * operator new(size_t m_size)
                 ^
ddmd/root/newdelete.c:36:15: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘delete’
 void operator delete(void *p)

Does anyone know what I am doing wrong?

Looks like a C compiler is used instead of a C++ compiler. Despite the extension, dmd's *.c files are C++ code.

Yes, that's what I thought - redhat has gcc, but not g++.  There must
be a needed compile option...

Yes - I needed to install gcc-c++, not g++.  That fixed everything.
