[ale] Problems compiling f2c 1.1 libs

[John M. Mills]

I managed (just) to build f2c and the static libf2c.a, but am getting tied in
knots trying to build the shared libs.  The system thrashes for 5 minutes or
so (can only get a few characters per minute even to a console screen), then
the log shows:

... libF77/getarg_.o(.te xt+0x27): undefined reference to `xargc'
... libF77/getarg_.o(.text+0x2e): undefine d reference to `xargv'

and a simlar complaint on two other modules.  Looking at the source, getarg_.c:
******
...
#ifdef KR_headers
VOID getarg_(n, s, ls) ftnint *n; register char *s; ftnlen ls;
#else
void getarg_(ftnint *n, register char *s, ftnlen ls)
#endif
{
extern int xargc;
extern char **xargv;
register char *t;
register int i;

if(*n>=0 && *n<xargc)
        t = xargv[*n];
...
*****

These are declared in main.c:
*****
...
int xargc;
char **xargv;

#ifdef KR_headers
main(argc, argv) int argc; char **argv;
#else
main(int argc, char **argv)
#endif
{
xargc = argc;
xargv = argv;
...
*****
Any ideas?  I'm using gcc 2.6.3.

Thanks --jmm--
