If you meant 'main' could be prefixed to '_main' for example, then GDB
can get rid of the prefix on display. On mingw target, function 'foo'
is prefixed to '_foo', but GDB still shows 'foo' rather than '_foo'.
$ i686-w64-mingw32-objdump -t 2.exe | grep foo
[ 64](sec 1)(fl 0x00)(ty 20)(scl 3) (nx 1) 0x00000560 _foo
Dump of assembler code from 0x401560 to 0x401565:
0x00401560 <foo+0>: push %ebp
0x00401561 <foo+1>: mov %esp,%ebp
