cannot compile multiple .c files at once

[rofl0r]

cparser a.c b.c c.c -o foo
./src/driver/c_driver.c:761: panic in build_firm_ir: compiling multiple files/translation units not yet supported
Aborted

this is a major bummer for me as it does not allow me to use my build system RcB2 with cparser.

can't we just compile each file on its own, write it somewhere to tmp, and then link the whole bunch together when the compiler is used liked this ?
