[R-SIG-Mac] package compilation failure

[Marco Scutari]

Hi all.

I've recently uploaded a package to CRAN. It build fine on both
Linux (32 and 64 bit) and Windows, but fails on MacOSX because
of C90 vs C99 issues:

Since I've no MacOSX machine at hand, I would like to ask you:
why C99 is not the default for gcc on MacOSX? Is it safe to force
gcc to use C99 with either -std=c99 o -std=gnu99?

Thanks in advance.
