What is the significant number of characters in idetifiers in gcc

I'm interested in doing common subexpression elimination on
mathematical
expressions in Mathematica syntax, and generate C/C++ code from them.
However some ways to generate unique identifiers can lead to very
long names
From the GCC 4.0.1 manual:
The number of significant initial characters in an identifier (C90
6.1.2, C90 and C99 5.2.4.1, C99 6.4.2).
For internal names, all characters are significant. For external
names, the number of significant characters are defined by the
linker; for almost all targets, all characters are significant.
