I have found what I believe to be a bug in cpp version 1.34.
The problem is that macros are not expanded if they appear
as operands to the concatenation operator. The configuration
is "config.gcc sun3".
$ cat bug.c
#define PREFIX abc_
#define XYZ(name) PREFIX ## name()
main ()
{
XYZ(func);
}
$ gcc -v -E bug.c
gcc version 1.34
/usr/local/lib/gcc-cpp -v -undef -D__GNUC__ -Dmc68000 -Dsun -Dunix -D__mc68000__ -D__sun__ -D__unix__ -D__HAVE_68881__ -Dmc68020 bug.c
GNU CPP version 1.34
# 1 "bug.c"
main ()
{
PREFIXfunc() ;
}
