`LINKFAIL'
==========
If the above command failed due to an unresolved reference
to strtoul, _strtoul, bsearch, _bsearch, or similar, see
[info -f g77 M LINKFAIL] (a node in the g77 documentation)
for information on what causes this, how to work around
the problem by editing ${srcdir}/proj.c, and what else to do.
Note:Missing strtoul or bsearch, for more information on this
problem, which occurs only in releases of `g77' based on `gcc'. (It
does not occur in `egcs'.)
On AIX 4.1, `g77' might not build with the native (non-GNU) tools
due to a linker bug in coping with the `-bbigtoc' option which leads to
a `Relocation overflow' error. The GNU linker is not recommended on
current AIX versions, though; it was developed under a now-unsupported
version. This bug is said to be fixed by `update PTF U455193 for APAR
IX75823'.
Compiling with `-mminimal-toc' might solve this problem, e.g. by
adding
BOOT_CFLAGS='-mminimal-toc -O2 -g'
to the `make bootstrap' command line.
