config.h in that region with autoconf 2.52
<extract>
/* Define if you have the `initgroups' function. */
#define HAVE_INITGROUPS 1


#if !defined(HAVE_INITGROUPS_PROTO)
#ifdef __cplusplus
extern "C" {
#endif
int initgroups(const char *, gid_t);
#ifdef __cplusplus
}
#endif
#endif


/* Define if you have the initgroups prototype */
#define HAVE_INITGROUPS_PROTO 1
</extract>

The config.log segment looks like:
<extract>
configure:31123: checking for initgroups
configure:31163: g++ -c -Wnon-virtual-dtor -Wno-long-long -Wundef -Wall -W -Wpointer-arith -Wwrite-strings -ansi -D_XOPEN_SO
URCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion -Wchar-subscripts -O2 -Wformat-security -Wmissing-format-attribute -fno-exc
eptions -fno-check-new -fno-common -pedantic-errors  -DQT_THREAD_SUPPORT  -D_REENTRANT conftest.cc >&5
configure:31166: $? = 0
configure:31169: test -s conftest.o
configure:31172: $? = 0
configure:31191: result: yes
configure:31194: checking if initgroups needs custom prototype
configure:31278: result: no
</extract>

The results for 2.57 are just the same (the applicable section in config.log
appears identical), except the ordering in config.h is different in 2.57, where
all the #define's are at the top, and the conditional prototypes are at the
bottom of the file.

OK, the config.h segment with 2.52 for the unsetenv stuff looks like:
<extract>
/* Define if you have unsetenv */
#define HAVE_UNSETENV 1


#if !defined(HAVE_UNSETENV_PROTO)
#ifdef __cplusplus
extern "C" {
#endif
void unsetenv (const char *);
#ifdef __cplusplus
}
#endif
#endif


/* Define if you have the unsetenv prototype */
#define HAVE_UNSETENV_PROTO 1
</extract>

and its the same problem. Basically 2.52 is generating bogus
config.h. 

A quick search through the Changelog for 2.57 didn't show 
anything indicative - maybe a binary search of autoconf 
versions?
