Unlikely.  You would need extern "C" to avoid C++ mangling.

The usual alternatives are:
a) with an obsolete Fortran, change your naming on the C side to match
what your Fortran does.  C has had the -D macro facility for this purpose
for about 30 years.  -DXYZ=XYZ__
b) use iso_c_binding and specify the name which will be seen by C linkage.
 This should motivate you to try gfortran or another current Fortran
instead of g77.
