Noel Chiappa scripsit:
The a.out symbol tables use 8-character fields to hold
symbol names. However,
C automagically and unavoidably prepends an _ to all externals (I forget
about automatics, registers, etc - too tired to check right now), making the
limit for C names 7 characters.
The _ was only for externals, including all procedure names. It prevented
collisions with names introduced into the assembly-language source or
in libc.
