While trying to build the latest version of openssl I
encounterd the following error:
gmake[2]: Entering directory

cc: acomp failed for randfile.c
gmake[2]: *** [randfile.o] Error 2
The comment in the header file is:
/*
* It is invalid to compile an XPG3, XPG4, XPG4v2, or
XPG5 application
* using c99. The same is true for POSIX.1-1990,
POSIX.2-1992, POSIX.1b,
* and POSIX.1c applications. Likewise, it is invalid
to compile an XPG6
* or a POSIX.1-2001 application with anything other
than a c99 or later
* compiler. Therefore, we force an error in both
cases.
*/
#if defined(_STDC_C99) && (defined(__XOPEN_OR_POSIX)

My environment is Solaris 10, Sun Studio 8 and I ran
configure with the following options:
./Configure solaris64-sparcv9-cc -DMD32_REG_T=int
--prefix=/opt/csw --openssldir
=/opt/csw/ssl
Apparently the Sun compiler defaults to c99
compatibility (i.e., -xc99=%all). The work around was
to insert the compiler option -xc99=%none into the
flags in the Makefile
