Subject: Enable lc_printf and friends handling of j, t, and z length modifier.
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=662bc34895ef0a6803c91aa6b9fcabc5d70b3d60;p=libfirm

Enable lc_printf and friends handling of j, t, and z length modifier.

Add a work-around for non-C99 MSCRT.

Use ir_printf now instead of printf.
