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
--=20
