I would be useful to get a more verbose error.

There remain a single problem:

$ ./bitcc -I../include -L../lib -l obj hello.bitc
gcc -O2  -I ../include -L ../lib -o bitc.out bitc.out.c -lbitc -lgcDans le fichier inclus à partir de bitc.out.c:8:
../include/bitc/runtime.h:49:2: erreur: #error "bitcc output requires C99 support"

I had to manually tell GCC which standard I want:

$ gcc -O2  -I ../include -L ../lib -o bitc.out bitc.out.c -lbitc -lgc --std=c99

No error. Fantastic! And it runs, too:

$ ./bitc.out
Hello, world!

The attached one-line patch seems to fix this. The second one is a
convenience: it adds an EOL after the output of GCC's invocation on
stderr.

Quickly,
Pierre
