Can't you compile with the -xc99 option? The Sun documentation says it's
supported, even with that old compiler:

'configure' should have deduced the -xc99 option for you; it tries
'-xc99=all' early on. Does that not work for you? The documentation
says '-xc99=%all' is required, but as I recall, the '%' was optional
even way back when.
That doesn't seem to be quite enough unfortunately:

If you look at the list of supported C99 features, it's:
* *C99 Keywords*
* *__func__* *Support*
* *Variable Length Arrays*
* *inline* *Specifier For Static Functions*
* *Commenting Code With //*
No mixing of declarations with statements. Ah well, this should be the
last time I have to do this.
