flexfax: Solaris 2.6 x86 build errors

["Joshua Berg" <jberg@enercon.org>]

I have downloaded hylafax v4.0pl2 and receive the following error trying to
build it with gcc v2.8.1:

/usr/local/bin/gcc      -I.././zlib  -D__ANSI_CPP__ -I. -I.. -I.././util  -I
.././util -I/usr/local/include -I.././regex -g -O -x c++ -c SendFaxJob.c++

SendFaxJob.c++: In method `unsigned char SendFaxJob::createJob(class
SendFaxClient &, class fxStr &)':
SendFaxJob.c++:501: no matching function for call to
`SendFaxClient::sendZData (int &, unsigned char (FaxClient::)(fxStr &, fxStr
&), fxStr &, fxStr &)'
FaxClient.h:273: candidates are: FaxClient::sendZData(int &, unsigned char
(FaxClient::*)(fxStr &, fxStr &), fxStr &, fxStr &)
*** Error code 1

Any help would be appreciated.
