It's possible now to compile/run an executable with user-defined sections, but now I see a problem with strip...

bash-2.01$ cat section.c
int __attribute__((section("mysection"))) i;
main(){printf("OK\n");}

bash-2.01$ gcc -o section section.c
bash-2.01$ objdump --headers section.exe

section.exe:     file format pei-i386

Sections:

The second section name contains some unprintable characters now.
