| Subject: | Failed to link on AIX because of missing Fputc() |
The perl module Math-BigInteger versjon 1.0 fail to link on AIX because
the function Fputc(), used in bn.c, is missing. I was unable to find any trace of this function anywhere, and suspect it is a typo in the code.
Changing Fputc() to fputc() solved the problem. It really puzzles me
that the code was able to compile and link on all the other platforms
I tried, Linux, HP/UX, Irix, Solaris, Tru64 Unix and Mac OS X. The
new code still work on the other platforms. Here is a patch to fix the
problem:
