See libgomp.map or
info ld
and search for VERSION command.

Just build the whole gcc tree.
If you are at the toplevel of gcc tree (i.e. directory that contains libgomp
subdirectory), do
mkdir obj
cd obj
../configure --disable-bootstrap --enable-languages=c,c++,fortran
make -j16 # or how many cores or threads you have
later on you can just
cd x86_64-*-linux*/libgomp
and in there
make -j16
make -k check

Yes, except that 8 consecutive spaces should be replaced by tab character.
So like:
{
if (...)
{
if (...)
{
if (...)
{
...
}
...
}
...
}
}

Variables shouldn't be defined in header files, they should be just declared
there (but I think ompd_dll_locations actually isn't required to be declared
in a header, all one needs to ensure is that it is exported from the shared
library (i.e. it is not static, and libgompd.map has ompd_dll_locations;
entry for it in global: section).
