Solaris apparently ships with at least 3 different versions of awk:
bobbi-harlow# ls -l /usr/bin/{n,}awk /usr/{xcu4,xpg4}/bin/awk
/usr/xcu4/bin/awk: No such file or directory
-r-xr-xr-x 1 bin bin 104036 May 3 1996 /usr/bin/awk
-r-xr-xr-x 1 bin bin 166200 May 2 1996 /usr/bin/nawk
-r-xr-xr-x 1 bin bin 108936 May 2 1996 /usr/xpg4/bin/awk
With peculiar manpage seperation and overlap:

It seems odd that /usr/xpg4/bin/awk is ostensibly covered by
both awk manpages. It seems even more odd given that
/usr/xcu4/bin/awk does not exist. The packages in question
are all installed, however:
bobbi-harlow# pkginfo | egrep 'SUNWesu|SUNWxcu4'
system SUNWesu Extended System Utilities
system SUNWxcu4 XCU4 Utilities
system SUNWxcu4t XCU4 make and sccs utilities
bobbi-harlow# pkginfo -l SUNWxcu4

pkginfo doesn't have a mechanism for saying what those installed
files *are*, of course (duh...).
So something seems broken there.
Anyhow, the awk(1) page states:
/usr/xpg4/bin/awk is described on the nawk(1) manual page.
/usr/bin/awk scans each input filename for lines that match
...
And makes no further mention of xcu4.
Anyhow, the USAGE section eventually states:
Other built-in functions include:
...
match(s, re)
returns the position in string s where the regular
expression re occurs, or 0 if it does not occur at
all.
bobbi-harlow# echo 1 | /usr/bin/awk '{print match("abc", /b/)}'
awk: syntax error near line 1
awk: illegal statement near line 1
bobbi-harlow# echo 1 | /usr/bin/nawk '{print match("abc", /b/)}'
2
bobbi-harlow# echo 1 | /usr/xpg4/bin/awk '{print match("abc", /b/)}'
2
bobbi-harlow#
Other string functions all seem to work.
